Basis of Presentation [Abstract]
Basis of Presentation	Basis of Presentation Liberty Global plc ( Liberty Global ) is a public limited company organized under the laws of England and Wales. In these notes, the terms “we,” “our,” “our company” and “us” may refer, as the context requires, to Liberty Global or collectively to Liberty Global and its subsidiaries. We are an international provider of video, broadband internet, fixed-line telephony, mobile and other communications services to residential customers and businesses, with consolidated operations at December 31, 2016 in more than 30 countries. In Europe, we provide residential and business-to-business ( B2B ) services in (i) the United Kingdom ( U.K. ) and Ireland through Virgin Media Inc. ( Virgin Media ), (ii) Germany through Unitymedia GmbH ( Unitymedia ), (iii) Belgium through Telenet Group Holding N.V. ( Telenet ), a 57.4% -owned subsidiary, and (iv) seven other European countries through UPC Holding B.V. ( UPC Holding ). In addition, through the December 31, 2016 completion of the Dutch JV Transaction (as defined and described in note 5 ), we provided residential and B2B services in the Netherlands through VodafoneZiggo Holding B.V., formerly known as Ziggo Group Holding B.V., which we refer to herein as “ Ziggo Group Holding .” Virgin Media , Unitymedia and UPC Holding are each wholly-owned subsidiaries of Liberty Global . The operations of Virgin Media , Unitymedia , Telenet , UPC Holding and, through December 31, 2016 , Ziggo Group Holding are collectively referred to herein as the “ European Division .” Outside of Europe, we provide residential and B2B services in (i) 18 countries, predominantly in Latin America and the Caribbean, through our wholly-owned subsidiary Cable & Wireless Communications Limited (formerly known as Cable & Wireless Communications Plc) ( CWC ), (ii) Chile through our wholly-owned subsidiary VTR.com SpA ( VTR ) and (iii) Puerto Rico through Liberty Cablevision of Puerto Rico LLC ( Liberty Puerto Rico ), an entity in which we hold a 60.0% ownership interest. CWC also provides (a) B2B services in certain other countries in Latin America and the Caribbean and (b) wholesale services over its sub-sea and terrestrial networks that connect over 30 markets in that region. CWC owns less than 100% of certain of its consolidated subsidiaries, including Cable & Wireless Panama, SA ( CWC Panama ) (a 49.0% -owned entity that owns most of our operations in Panama), The Bahamas Telecommunications Company Limited ( CWC BTC ) (a 49.0% -owned entity that owns all of our operations in the Bahamas), Cable & Wireless Jamaica Limited ( CWC Jamaica ) (an 82.0% -owned entity that owns the majority of our operations in Jamaica) and Cable & Wireless Barbados Limited ( CWC Barbados ) (an 81.1% -owned entity that owns the majority of our operations in Barbados). The operations of CWC , VTR and Liberty Puerto Rico are collectively referred to herein as the “ LiLAC Division .” 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 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 ). In these notes, the term “ Old Liberty Global Shares ” refers to our previously-outstanding Class A, Class B and Class C Liberty Global ordinary 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 impact of the LiLAC Transaction on our capitalization and earnings (loss) per share presentation has been reflected in these consolidated financial statements prospectively from July 1, 2015. Accordingly, (a) our net earnings (loss) attributed to Liberty Global Shares and LiLAC Shares relates to periods subsequent to July 1, 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) LGE Coral Holdco Limited ( LGE Coral ) and its subsidiaries, which include CWC , (ii) VTR Finance B.V. ( VTR Finance ) and its subsidiaries, which include VTR , (iii) Lila Chile Holding B.V. ( Lila Chile Holding ), which is the parent entity of VTR Finance , (iv) LiLAC Communications Inc. (formerly known as LiLAC Holdings Inc.) ( LiLAC Communications ) and its subsidiaries, which include Liberty Puerto Rico , and (v) 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 Communications . The “ Liberty Global Group ” comprises our businesses, assets and liabilities not attributed to the LiLAC Group , including Virgin Media , Ziggo Group Holding ( through December 31, 2016 ), Unitymedia , Telenet , UPC Holding , our corporate entities (excluding LiLAC Communications ) and certain other less significant entities. For additional information regarding our tracking share capital structure, including unaudited attributed financial information of the Liberty Global Group and the LiLAC Group , see Exhibit 99.1 to this Annual Report on Form 10-K. 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 consolidated financial statements. For additional information regarding our discontinued operation, see note 5 . Unless otherwise indicated, ownership percentages and convenience translations into United States ( U.S. ) dollars are calculated as of December 31, 2016

Accounting Policies [Abstract]
Accounting Changes and Recent Accounting Pronouncements	Accounting Changes and Recent Accounting Pronouncements Accounting Changes In April 2015, the Financial Accounting Standards Board ( FASB ) issued Accounting Standards Update ( ASU ) No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ( ASU 2015-03 ), which requires debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a reduction of debt, similar to the presentation of debt discounts. For public entities, ASU 2015-03 was effective for annual reporting periods beginning after December 15, 2015. We adopted ASU 2015-03 on January 1, 2016 and, accordingly, deferred financing costs are presented as a reduction of debt in our December 31, 2016 and 2015 consolidated balance sheets. Prior to the adoption of ASU 2015-03 , we presented deferred financing costs in other assets, net. Recent Accounting Pronouncements ASU 2014-09 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ( ASU 2014-09 ), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 , as amended by ASU No. 2015-14, will replace existing revenue recognition guidance when it becomes effective for annual and interim reporting periods beginning after December 15, 2017. This new standard permits the use of either the retrospective or cumulative effect transition method. We will adopt ASU 2014-09 effective January 1, 2018 using the cumulative effect transition method. While we are continuing to evaluate the effect that ASU 2014-09 will have on our consolidated financial statements, we have identified a number of our current revenue recognition policies that will be impacted by ASU 2014-09 , including the accounting for (i) time-limited discounts and free periods provided to our customers and (ii) certain up-front fees charged to our customers. These impacts are discussed below: • When we enter into contracts to provide services to our customers, we often provide time-limited discounts or free service periods. Under current accounting rules, we recognize revenue net of discounts during the promotional periods and do not recognize any revenue during free service periods. Under ASU 2014-09 , revenue recognition will be accelerated for these contracts as the impact of the discount or free service period will be recognized uniformly over the total contractual period. • When we enter into contracts to provide services to our customers, we often charge installation or other up-front fees. Under current accounting rules, installation fees related to services provided over our cable networks are recognized as revenue in the period during which the installation occurs to the extent these fees are equal to or less than direct selling costs. Under ASU 2014-09 , these fees will generally be deferred and recognized as revenue over the contractual period, or longer if the up-front fee results in a material renewal right. As the above revenue recognition changes have offsetting impacts and both result in a relatively minor shift in the timing of revenue recognition, we currently do not expect ASU 2014-09 to have a material impact on our reported revenue. ASU 2014-09 will also impact our accounting for certain upfront costs directly associated with obtaining and fulfilling customer contracts. Under our current policy, these costs are expensed as incurred unless the costs are in the scope of another accounting topic that allows for capitalization. Under ASU 2014-09 , the upfront costs that are currently expensed as incurred will be recognized as assets and amortized to other operating expenses over a period that is consistent with the transfer to the customers of the goods or services to which the assets relate, which we have generally interpreted to be the expected customer life. The impact of the accounting change for these costs will be dependent on numerous factors, including the number of new subscriber contracts added in any given period, but we expect the adoption of this accounting change will initially result in the deferral of a significant amount of operating and selling costs. The ultimate impact of adopting ASU 2014-09 for both revenue recognition and costs to obtain and fulfill contracts will depend on the promotions and offers in place during the period leading up to and after the adoption of ASU 2014-09 . ASU 2016-02 In February 2016, the FASB issued ASU No. 2016-02, Leases ( ASU 2016-02 ), which, for most leases, will result in lessees recognizing lease assets and lease liabilities on the balance sheet with additional disclosures about leasing arrangements. ASU 2016-02 requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach also includes a number of optional practical expedients an entity may elect to apply. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Although we are currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements, we expect the adoption of this standard will increase the number of leases to be accounted for as capital leases in our consolidated balance sheet. ASU 2016-09 In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation, Improvements to Employee Share-Based Payment Accounting ( ASU 2016-09 ), which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification within the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those fiscal years, with early adoption permitted. ASU 2016-09 will result in, among other matters, the immediate recognition for financial reporting purposes of excess tax benefits that currently are not recognized until such time as these tax benefits can be realized as a reduction of income taxes payable. ASU 2017-04 In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment ( ASU 2017-04 ), which eliminates the requirement to estimate the implied fair value of a reporting unit’s goodwill as determined following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, a company should recognize any goodwill impairment by comparing the fair value of a reporting unit to its carrying amount. ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We expect the adoption of ASU 2017-04

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. ( U.S. GAAP ) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used in accounting for, among other things, the valuation of acquisition-related assets and liabilities, allowances for uncollectible accounts, programming and copyright expenses, 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. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation, including the reclassification of deferred financing costs from other long-term assets to long-term debt and capital lease obligations and the reclassification of certain costs between programming and other direct costs of services, other operating and SG&A expenses. For additional information regarding the change in the classification of deferred financing costs, see “Accounting Changes” in note 2 . Principles of Consolidation The accompanying consolidated financial statements include our accounts and the accounts of all voting interest entities where we exercise a controlling financial interest through the ownership of a direct or indirect controlling voting interest and variable interest entities for which our company is the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation. Cash and Cash Equivalents and Restricted Cash Cash equivalents consist of money market funds and other investments that are readily convertible into cash and have maturities of three months or less at the time of acquisition. We record money market funds at the net asset value reported by the investment manager as there are no restrictions on our ability, contractual or otherwise, to redeem our investments at the stated net asset value reported by the investment manager. Restricted cash consists of cash held in restricted accounts, including cash held as collateral for debt and other compensating balances. Restricted cash amounts that are required to be used to purchase long-term assets or repay long-term debt are classified as long-term assets. All other cash that is restricted to a specific use is classified as current or long-term based on the expected timing of the disbursement. At December 31, 2016 and 2015 , our current and long-term restricted cash balances aggregated $39.1 million and $127.9 million , respectively. Our significant non-cash investing and financing activities are disclosed in our consolidated statements of equity and in notes 4 , 7 , 9 , and 10 . Trade Receivables Our trade receivables are reported net of an allowance for doubtful accounts. Such allowance aggregated $193.4 million and $115.7 million at December 31, 2016 and 2015 , respectively. The allowance for doubtful accounts is based upon our assessment of probable loss related to uncollectible accounts receivable. We use a number of factors in determining the allowance, including, among other things, collection trends, prevailing and anticipated economic conditions and specific customer credit risk. The allowance is maintained until either payment is received or the likelihood of collection is considered to be remote. Concentration of credit risk with respect to trade receivables is limited due to the large number of customers and their dispersion across many different countries worldwide. We also manage this risk by disconnecting services to customers whose accounts are delinquent. Investments We make elections, on an investment-by-investment basis, as to whether we measure our investments at fair value. Such elections are generally irrevocable. With the exception of those investments over which we exercise significant influence, we generally elect the fair value method. For those investments over which we exercise significant influence, we generally elect the equity method. Under the fair value method, investments are recorded at fair value and any changes in fair value are reported in realized and unrealized gains or losses due to changes in fair values of certain investments and debt, net, in our consolidated statements of operations. All costs directly associated with the acquisition of an investment to be accounted for using the fair value method are expensed as incurred. Under the equity method of accounting, investments are recorded at cost and are subsequently increased or reduced to reflect our share of income or losses of the investee. All costs directly associated with the acquisition of an investment to be accounted for using the equity method are included in the carrying amount of the investment. For additional information regarding our fair value and equity method investments, see notes 6 and 8 . Under the equity method, investments, originally recorded at cost, are adjusted to recognize our share of net earnings or losses of the affiliates as they occur rather than as dividends or other distributions are received, with our recognition of losses generally limited to the extent of our investment in, and advances and commitments to, the investee. The portion of the difference between our investment and our share of the net assets of the investee that represents goodwill is not amortized, but continues to be considered for impairment. Intercompany profits on transactions with equity affiliates for which assets remain on our or our investee’s balance sheet are eliminated to the extent of our ownership in the investee. Dividends from publicly-traded investees that are not accounted for under the equity method are recognized when declared as dividend income in our consolidated statements of operations. Dividends from our equity method investees and all of our privately-held investees are reflected as reductions of the carrying values of the applicable investments. Dividends that are deemed to be (i) returns on our investments are included in cash flows from operating activities in our consolidated statements of cash flows and (ii) returns of our investments are included in cash flows from investing activities in our consolidated statements of cash flows. We continually review all of our equity and cost method investments to determine whether a decline in fair value below the cost basis is other-than-temporary. The primary factors we consider in our determination are the extent and length of time that the fair value of the investment is below our company’s carrying value and the financial condition, operating performance and near-term prospects of the investee, changes in the stock price or valuation subsequent to the balance sheet date, and the impacts of exchange rates, if applicable. If the decline in fair value of an equity or cost method investment is deemed to be other-than-temporary, the cost basis of the security is written down to fair value. Realized gains and losses are determined on an average cost basis. Securities transactions are recorded on the trade date. Financial Instruments Due to the short maturities of cash and cash equivalents, restricted cash, short-term liquid investments, trade and other receivables, other current assets, accounts payable, accrued liabilities and other accrued and current liabilities, their respective carrying values approximate their respective fair values. For information concerning the fair values of certain of our investments, derivatives and debt, see notes 6 , 7 and 10 , respectively. For information regarding how we arrive at certain of our fair value measurements, see note 8 . Derivative Instruments All derivative instruments, whether designated as hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative instrument is not designated as a hedge, changes in the fair value of the derivative instrument are recognized in earnings. If the derivative instrument is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative instrument are recorded in other comprehensive earnings or loss and subsequently reclassified into our consolidated statements of operations when the hedged forecasted transaction affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings. With the exception of a limited number of our foreign currency forward contracts, we do not apply hedge accounting to our derivative instruments. The net cash received or paid related to our derivative instruments is classified as an operating, investing or financing activity in our 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 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 in our consolidated statement of cash flows. For information regarding our derivative instruments, see note 7 . Property and Equipment Property and equipment are stated at cost less accumulated depreciation. We capitalize costs associated with the construction of new cable and mobile transmission and distribution facilities and the installation of new cable services. Capitalized construction and installation costs include materials, labor and other directly attributable costs. Installation activities that are capitalized include (i) the initial connection (or drop) from our cable system to a customer location, (ii) the replacement of a drop and (iii) the installation of equipment for additional services, such as digital cable, telephone or broadband internet service. The costs of other customer-facing activities, such as reconnecting customer locations where a drop already exists, disconnecting customer locations and repairing or maintaining drops, are expensed as incurred. Interest capitalized with respect to construction activities was not material during any of the periods presented. Capitalized internal-use software is included as a component of property and equipment. We capitalize internal and external costs directly associated with the development of internal-use software. We also capitalize costs associated with the purchase of software licenses. Maintenance and training costs, as well as costs incurred during the preliminary stage of an internal-use software development project, are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful life of the underlying asset. Equipment under capital leases is amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Useful lives used to depreciate our property and equipment are assessed periodically and are adjusted when warranted. The useful lives of cable and mobile distribution systems that are undergoing a rebuild are adjusted such that property and equipment to be retired will be fully depreciated by the time the rebuild is completed. For additional information regarding the useful lives of our property and equipment, see note 9 . Additions, replacements and improvements that extend the asset life are capitalized. Repairs and maintenance are charged to operations. We recognize a liability for asset retirement obligations in the period in which it is incurred if sufficient information is available to make a reasonable estimate of fair values. Asset retirement obligations may arise from the loss of rights of way that we obtain from local municipalities or other relevant authorities. Under certain circumstances, the authorities could require us to remove our network equipment from an area if, for example, we were to discontinue using the equipment for an extended period of time or the authorities were to decide not to renew our access rights. However, because the rights of way are integral to our ability to deliver broadband communications services to our customers, we expect to conduct our business in a manner that will allow us to maintain these rights for the foreseeable future. In addition, we have no reason to believe that the authorities will not renew our rights of way and, historically, renewals have been granted. We also have obligations in lease agreements to restore the property to its original condition or remove our property at the end of the lease term. Sufficient information is not available to estimate the fair value of our asset retirement obligations in certain of our lease arrangements. This is the case for long-term lease arrangements in which the underlying leased property is integral to our operations, there is not an acceptable alternative to the leased property and we have the ability to indefinitely renew the lease. Accordingly, for most of our rights of way and certain lease agreements, the possibility is remote that we will incur significant removal costs in the foreseeable future and, as such, we do not have sufficient information to make a reasonable estimate of fair value for these asset retirement obligations. As of December 31, 2016 and 2015 , the recorded value of our asset retirement obligations was $96.3 million and $63.9 million , respectively. Intangible Assets Our primary intangible assets relate to goodwill, customer relationships and cable television franchise rights. Goodwill represents the excess purchase price over the fair value of the identifiable net assets acquired in a business combination. Customer relationships and cable television franchise rights are initially recorded at their fair values in connection with business combinations. Goodwill and other intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually. Intangible assets with finite lives are amortized on a straight-line basis over their respective estimated useful lives to their estimated residual values, and reviewed for impairment. We do not amortize our cable television franchise rights and certain other intangible assets as these assets have indefinite lives. For additional information regarding the useful lives of our intangible assets, see note 9 . Impairment of Property and Equipment and Intangible Assets When circumstances warrant, we review the carrying amounts of our property and equipment and our intangible assets (other than goodwill and other indefinite-lived intangible assets) to determine whether such carrying amounts continue to be recoverable. Such changes in circumstance may include (i) an expectation of a sale or disposal of a long-lived asset or asset group, (ii) adverse changes in market or competitive conditions, (iii) an adverse change in legal factors or business climate in the markets in which we operate and (iv) operating or cash flow losses. For purposes of impairment testing, long-lived assets are grouped at the lowest level for which cash flows are largely independent of other assets and liabilities, generally at or below the reporting unit level (see below). If the carrying amount of the asset or asset group is greater than the expected undiscounted cash flows to be generated by such asset or asset group, an impairment adjustment is recognized. Such adjustment is measured by the amount that the carrying value of such asset or asset group exceeds its fair value. We generally measure fair value by considering (a) sale prices for similar assets, (b) discounted estimated future cash flows using an appropriate discount rate and/or (c) estimated replacement cost. Assets to be disposed of are recorded at the lower of their carrying amount or fair value less costs to sell. We evaluate goodwill and other indefinite-lived intangible assets (primarily cable television franchise rights) for impairment at least annually on October 1 and whenever facts and circumstances indicate that their carrying amounts may not be recoverable. For impairment evaluations with respect to both goodwill and other indefinite-lived intangibles, we first make a qualitative assessment to determine if the goodwill or other indefinite-lived intangible may be impaired. In the case of goodwill, if it is more-likely-than-not that a reporting unit’s fair value is less than its carrying value, we then compare the fair value of the reporting unit to its respective carrying amount. A reporting unit is an operating segment or one level below an operating segment (referred to as a “component”). If the carrying value of a reporting unit were to exceed its fair value, we would then compare the implied fair value of the reporting unit’s goodwill to its carrying amount, and any excess of the carrying amount over the fair value would be charged to operations as an impairment loss. With respect to other indefinite-lived intangible assets, if it is more-likely-than-not that the fair value of an indefinite-lived intangible asset is less than its carrying value, we then estimate its fair value and any excess of the carrying value over the fair value is also charged to operations as an impairment loss. Income Taxes Income taxes are accounted for under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts and income tax basis of assets and liabilities and the expected benefits of utilizing net operating loss and tax credit carryforwards, using enacted tax rates in effect for each taxing jurisdiction in which we operate for the year in which those temporary differences are expected to be recovered or settled. We recognize the financial statement effects of a tax position when it is more-likely-than-not, based on technical merits, that the position will be sustained upon examination. Net deferred tax assets are then reduced by a valuation allowance if we believe it is more-likely-than-not such net deferred tax assets will not be realized. Certain of our valuation allowances and tax uncertainties are associated with entities that we acquired in business combinations. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. Deferred tax liabilities related to investments in foreign subsidiaries and foreign corporate joint ventures that are essentially permanent in duration are not recognized until it becomes apparent that such amounts will reverse in the foreseeable future. In order to be considered essentially permanent in duration, sufficient evidence must indicate that the foreign subsidiary has invested or will invest its undistributed earnings indefinitely, or that earnings will be remitted in a tax-free liquidation. Interest and penalties related to income tax liabilities are included in income tax benefit or expense in our consolidated statements of operations. For additional information on our income taxes, see note 11 . Foreign Currency Translation and Transactions The reporting currency of our company is the U.S. dollar. The functional currency of our foreign operations generally is the applicable local currency for each foreign subsidiary and equity method investee. Assets and liabilities of foreign subsidiaries (including intercompany balances for which settlement is not anticipated in the foreseeable future) are translated at the spot rate in effect at the applicable reporting date. With the exception of certain material transactions, the amounts reported in our consolidated statements of operations are translated at the average exchange rates in effect during the applicable period. The resulting unrealized cumulative translation adjustment, net of applicable income taxes, is recorded as a component of accumulated other comprehensive earnings or loss in our consolidated statements of equity. With the exception of certain material transactions, the cash flows from our operations in foreign countries are translated at the average rate for the applicable period in our consolidated statements of cash flows. The impacts of material transactions generally are recorded at the applicable spot rates in our consolidated statements of operations and cash flows. The effect of exchange rates on cash balances held in foreign currencies are separately reported in our consolidated statements of cash flows. Transactions denominated in currencies other than our or our subsidiaries’ functional currencies are recorded based on exchange rates at the time such transactions arise. Changes in exchange rates with respect to amounts recorded in our consolidated balance sheets related to these non-functional currency transactions result in transaction gains and losses that are reflected in our consolidated statements of operations as unrealized (based on the applicable period end exchange rates) or realized upon settlement of the transactions. Revenue Recognition Service Revenue — Cable Networks. We recognize revenue from the provision of video, broadband internet and fixed-line telephony services over our cable network to customers in the period the related services are provided. Installation revenue (including reconnect fees) related to services provided over our cable network is recognized as revenue in the period during which the installation occurs to the extent these fees are equal to or less than direct selling costs, which costs are expensed as incurred. To the extent installation revenue exceeds direct selling costs, the excess revenue is deferred and amortized over the average expected subscriber life. Sale of Multiple Products and Services. We sell video, broadband internet, fixed-line telephony and, in most of our markets, mobile services to our customers in bundled packages at a rate lower than if the customer purchased each product on a standalone basis. Revenue from bundled packages generally is allocated proportionally to the individual services based on the relative standalone price for each respective service. Mobile Revenue — General. Consideration from mobile contracts is allocated to the airtime service element and the handset service element based on the relative standalone prices of each element. The amount of consideration allocated to the handset is limited to the amount that is not contingent upon the delivery of future airtime services. Certain of our operations that provide mobile services offer handsets under a subsidized contract model, whereby upfront revenue recognition is limited to the upfront cash collected from the customer as the remaining monthly fees to be received from the customer, including fees that may be associated with the handset, are contingent upon delivering future airtime services. At certain of our operations, mobile customers may choose to enter into two distinct contractual relationships: (i) a mobile handset contract and (ii) a mobile airtime services contract (a Split-contract Program ). Under the mobile handset contract, the customer takes full title to the handset upon delivery and typically has the option to either (a) pay for the handset in cash upon delivery or (b) pay for the handset in installments over a contractual period. Under these arrangements, the handset installment payments are not contingent upon delivering future airtime services and the consideration allocated to the handset is not limited to the upfront cash collected. Mobile Revenue — Airtime Services. We recognize revenue from mobile services in the period the related services are provided. Revenue from pre-pay customers is recorded as deferred revenue prior to the commencement of services and revenue is recognized as the services are rendered or usage rights expire. Mobile Revenue — Handset Revenue. Arrangement consideration allocated to handsets is recognized as revenue when the goods have been delivered and title has passed. For customers under a mobile handset installment contract that is independent of a mobile airtime services contract, revenue is recognized upon delivery only if collectibility is reasonably assured. Our assessment of collectibility is based principally on internal and external credit assessments as well as historical collection information for similar customers. To the extent that collectibility of installment payments from the customer is not reasonably assured upon delivery of the handset, handset revenue is recognized on a cash basis as customer payments are received. B2B Revenue. We defer upfront installation and certain nonrecurring fees received on B2B contracts where we maintain ownership of the installed equipment. The deferred fees are amortized into revenue on a straight-line basis over the term of the arrangement or the expected period of performance. Promotional Discounts. For subscriber promotions, such as discounted or free services during an introductory period, revenue is recognized only to the extent of the discounted monthly fees charged to the subscriber, if any. Subscriber Advance Payments and Deposits. Payments received in advance for the services we provide are deferred and recognized as revenue when the associated services are provided. Sales, Use and Other Value-Added Taxes ( VAT ). Revenue is recorded net of applicable sales, use and other value-added taxes. Share-based Compensation We recognize all share-based payments to employees, including grants of employee share-based incentive awards, based on their grant-date fair values and our estimates of forfeitures. We recognize the grant-date fair value of outstanding awards as a charge to operations over the vesting period. The cash benefits of tax deductions in excess of deferred taxes on recognized share-based compensation expense are reported as a financing cash flow. Payroll taxes incurred in connection with the vesting or exercise of our share-based incentive awards are recorded as a component of share-based compensation expense in our consolidated statements of operations. We use the straight-line method to recognize share-based compensation expense for our outstanding share awards that do not contain a performance condition and the accelerated expense attribution method for our outstanding share awards that contain a performance condition and vest on a graded basis. The grant date fair values for options, share appreciation rights ( SAR s ) and performance-based share appreciation rights ( PSAR s ) are estimated using the Black-Scholes option pricing model, and the grant date fair values for restricted share units ( RSU s ) and performance-based restricted share units ( PSU s) are based upon the closing share price of Liberty Global ordinary shares on the date of grant. We calculate the expected life of options and SAR s granted by Liberty Global to employees based on historical exercise trends. The expected volatility for options and SAR s related to Liberty Global Shares is generally based on a combination of (i) historical volatilities of Liberty Global Shares for a period equal to the expected average life of the awards and (ii) volatilities implied from publicly-traded options for Liberty Global Shares . The expected volatility for options and SARs related to LiLAC Shares is generally based on a combination of (a) historical volatilities of LiLAC Shares for a period equal to the expected average life of the award and, if this data is unavailable, historical volatilities of ordinary shares of a relevant peer group for a period equal to the expected average life of the award, and (b) volatilities implied from publicly-traded options for LiLAC Shares where available. We generally issue new Liberty Global ordinary shares when Liberty Global options or SAR s are exercised and when RSU s and PSU s vest. Although we repurchase Liberty Global ordinary shares from time to time, the parameters of our share purchase and redemption activities are not established solely with reference to the dilutive impact of our share-based compensation plans. For additional information regarding our share-based compensation, see note 13 . Litigation Costs Legal fees and related litigation costs are expensed as incurred. Earnings or Loss per Share Basic earnings or loss per share ( EPS ) is computed by dividing net earnings or loss by the weighted average number of shares outstanding for the period. Diluted earnings or loss per share presents the dilutive effect, if any, on a per share basis of potential shares (e.g., options, SAR s, PSAR s, RSU s and convertible securities) as if they had been exercised, vested or converted at the beginning of the periods presented. The details of our net earnings (loss) attributable to holders of Liberty Global Shares , LiLAC Shares and Old Liberty Global Shares are set forth below: Year ended December 31, 2016 2015 2014 in millions Net earnings (loss) attributable to holders of: Liberty Global Shares (a) $ 1,941.1 $ (167.5 ) $ — LiLAC Shares (a) (235.8 ) 17.2 — Old Liberty Global Shares (b): Loss from continuing operations — (1,002.2 ) (1,028.5 ) Earnings from discontinued operation — — 333.5 — (1,002.2 ) (695.0 ) Net earnings (loss) attributable to Liberty Global shareholders $ 1,705.3 $ (1,152.5 ) $ (695.0 ) _______________ (a) The amounts presented for the year ended December 31, 2015 relate to the period from July 1, 2015 through December 31, 2015. (b) The amounts presented for the year ended December 31, 2015 relate to the period from January 1, 2015 through June 30, 2015.

(b) The amount presented for the year ended December 31, 2015 relates 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 year ended December 31, 2016 are set forth in the table below: Numerator: Net earnings attributable to holders of Liberty Global Shares (basic EPS computation) (in millions) $ 1,941.1 Interest expense on Virgin Media’s 6.50% convertible senior notes 1.7 Net earnings attributable to holders of Liberty Global Shares (diluted EPS computation) (in millions) $ 1,942.8 Denominator: Weighted average ordinary shares (basic EPS computation) 889,790,968 Incremental shares attributable to the assumed exercise of outstanding options, SARs and PSARs and the release of share units upon vesting (treasury stock method) 7,819,514 Virgin Media’s 6.50% convertible senior notes 2,359,172 Weighted average ordinary shares (diluted EPS computation) 899,969,654 We reported a loss from continuing operations attributable to holders of Liberty Global Shares for the period from July 1, 2015 through December 31, 2015 . Therefore, the potentially dilutive effect at December 31, 2015 of the following items was not included in the computation of diluted loss per share attributable to holders of Liberty Global Shares because their inclusion would have been anti-dilutive to the computation or, in the case of certain PSU s and performance grant units ( 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 43.3 million , (ii) the aggregate number of shares issuable pursuant to PSU s and PGUs of approximately 4.5 million and (iii) the aggregate number of shares issuable pursuant to obligations that may be settled in cash or shares of approximately 2.7 million . LiLAC Shares . We reported a loss attributable to holders of LiLAC Shares during the year ended December 31, 2016 . Theref

Business Combinations [Abstract]
Acquisitions	Acquisitions Pending Acquisitions SFR BeLux . On December 22, 2016, a subsidiary of Telenet entered into a definitive agreement to acquire Coditel Brabant sprl, operating under the SFR brand ( SFR BeLux ), for €400.0 million ( $421.9 million ) on a cash and debt free basis. SFR BeLux provides cable services to households and businesses in Brussels, Wallonia and Luxembourg and offers mobile services in Belgium through a mobile virtual network operator ( MVNO ) agreement with BASE , as defined and described below. Telenet intends to finance the acquisition of SFR BeLux through a combination of existing cash and cash equivalents and available liquidity under its revolving credit facilities. The transaction is subject to customary closing conditions, including approval from the relevant competition authorities, and is expected to close during the second half of 2017. Multimedia . On October 18, 2016, our subsidiary UPC Polska SP Z.o.o. entered into a definitive agreement to acquire the cable business of Multimedia Polska S.A. ( Multimedia ), the third-largest cable operator in Poland, for cash consideration of PLN 3.0 billion ( $718.2 million ), which is equal to the enterprise value assigned to Multimedia for purposes of this transaction. We intend to finance the acquisition of Multimedia with existing liquidity. The final purchase price is subject to potential downward adjustments for the operational and financial performance of Multimedia prior to closing. The transaction is subject to customary closing conditions, including regulatory approval, and is expected to close in late 2017 or early 2018. 2016 Acquisitions CWC . On May 16, 2016 , we acquired CWC for shares of Liberty Global (the CWC Acquisition ). Under the terms of the transaction, CWC shareholders received in the aggregate: 31,607,008 Class A Liberty Global Shares , 77,379,774 Class C Liberty Global Shares , 3,648,513 Class A LiLAC Shares and 8,939,316 Class C LiLAC Shares . Further, immediately prior to the acquisition, CWC declared a special cash dividend (the Special Dividend ) to its shareholders in the amount of £0.03 ( $0.04 at the transaction date) per CWC share. The Special Dividend was paid to CWC shareholders promptly following the closing and the payment, together with fees and expenses related to the acquisition, was funded with CWC liquidity, including incremental debt borrowings, and LiLAC Group corporate liquidity. We acquired CWC in order to achieve certain financial, operational and strategic benefits through the integration of CWC with our existing operations in the LiLAC Group . The CWC Acquisition triggered regulatory approval requirements in certain jurisdictions in which CWC operates. The regulatory authorities in certain of these jurisdictions, including the Bahamas, Jamaica, Trinidad and Tobago, the Seychelles and the Cayman Islands, have not completed their review of the CWC Acquisition or granted their approval. While we expect to receive all outstanding approvals, such approvals may include binding conditions or requirements that could have an adverse impact on CWC ’s operations and financial condition. For accounting purposes, the CWC Acquisition was treated as the acquisition of CWC by Liberty Global . In this regard, the equity and cash consideration paid to acquire CWC is set forth below (in millions): Class A Liberty Global Shares (a) $ 1,167.2 Class C Liberty Global Shares (a) 2,803.5 Class A LiLAC Shares (a) 144.1 Class C LiLAC Shares (a) 375.3 Special Dividend (b) 193.8 Total $ 4,683.9 _______________ (a) Represents the fair value of the 31,607,008 Class A Liberty Global Shares , 77,379,774 Class C Liberty Global Shares , 3,648,513 Class A LiLAC Shares and 8,939,316 Class C LiLAC Shares issued to CWC shareholders in connection with the CWC Acquisition . These amounts are based on the market price per share at closing on May 16, 2016 of $36.93 , $36.23 , $39.50 and $41.98 , respectively. (b) Represents the Special Dividend of £0.03 ( $0.04 at the transaction date) per CWC share paid pursuant to the scheme of arrangement based on 4,433,222,313 outstanding shares of CWC on May 16, 2016 . We have accounted for the CWC Acquisition using the acquisition method of accounting, whereby the total purchase price was allocated to the acquired identifiable net assets of CWC based on assessments of their respective fair values, and the excess of the purchase price over the fair values of these identifiable net assets was allocated to goodwill. 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, customer relationships, trademarks, noncontrolling interests and income taxes. A summary of the purchase price and the preliminary opening balance sheet of CWC at the May 16, 2016 acquisition date is presented in the following table (in millions): Cash and cash equivalents $ 210.8 Other current assets 583.2 Property and equipment, net 2,908.1 Goodwill (a) 5,544.3 Intangible assets subject to amortization, net (b) 1,266.0 Other assets, net 579.2 Current portion of debt and capital lease obligations (94.2 ) Other accrued and current liabilities (750.1 ) Long-term debt and capital lease obligations (3,308.0 ) Other long-term liabilities (803.6 ) Noncontrolling interests (c) (1,451.8 ) Total purchase price (d) $ 4,683.9 _______________ (a) The goodwill recognized in connection with the CWC Acquisition is primarily attributable to (i) the ability to take advantage of CWC ’s existing terrestrial and sub-sea networks to gain immediate access to potential customers and (ii) synergies that are expected to be achieved through the integration of CWC with other operations in the LiLAC Group . (b) Amount primarily includes intangible assets related to customer relationships. At May 16, 2016 , the preliminary assessment of the weighted average useful life of CWC ’s intangible assets was approximately eight years . (c) Represents the estimated aggregate fair value of the noncontrolling interests in CWC ’s subsidiaries as of May 16, 2016 . (d) Excludes direct acquisition costs of $132.0 million , including $118.5 million incurred during 2016, which are included in impairment, restructuring and other operating items, net, in our consolidated statements of operations. Following completion of the CWC Acquisition , we attributed CWC to the LiLAC Group , with the Liberty Global Group being granted an inter-group interest in the LiLAC Group representing the fair value (as determined by our board of directors) of the Liberty Global Shares issued as part of the purchase consideration. On July 1, 2016, we distributed (as a bonus issue) 117,430,965 LiLAC Shares to Liberty Global Group shareholders on a pro-rata basis (the LiLAC Distribution ), thereby eliminating the Liberty Global Group 's inter-group interest in the LiLAC Group . The LiLAC Distribution was accounted for prospectively effective July 1, 2016. BASE . On February 11, 2016 , Telenet acquired Telenet Group BVBA, formerly known as BASE Company NV ( BASE ), for a cash purchase price of €1,318.9 million ( $1,494.3 million at the transaction date) (the BASE Acquisition ). BASE is the third-largest mobile network operator in Belgium. We expect that the BASE Acquisition will provide Telenet with cost-effective long-term mobile access to effectively compete for future growth opportunities in the Belgium mobile market. The BASE Acquisition was funded through a combination of €1.0 billion ( $1.1 billion at the transaction date) of new debt facilities and existing liquidity of Telenet . The acquisition was approved by the European Commission subject to Telenet ’s agreement to divest both the JIM Mobile prepaid customer base and BASE ’s 50% stake in Viking Co NV ( Viking ) to MEDIALAAN NV. In February 2016, Telenet completed the sale of its stake in Viking . The divestiture of the JIM Mobile prepaid customer base is expected to occur during the third quarter of 2017. We have accounted for the BASE Acquisition using the acquisition method of accounting, whereby the total purchase price was allocated to the acquired identifiable net assets of BASE based on assessments of their respective fair values, and the excess of the purchase price over the fair values of these identifiable net assets was allocated to goodwill. A summary of the purchase price and the opening balance sheet of BASE at the February 11, 2016 acquisition date is presented in the following table. The opening balance sheet presented below reflects our final purchase price allocation (in millions): Cash and cash equivalents $ 160.1 Other current assets 148.3 Property and equipment, net 811.4 Goodwill (a) 330.7 Intangible assets subject to amortization, net: Mobile spectrum (b) 261.0 Customer relationships (c) 115.0 Trademarks (d) 40.7 Other assets, net 10.5 Other accrued and current liabilities (290.0 ) Other long-term liabilities (93.4 ) Total purchase price (e) $ 1,494.3 _______________ (a) The goodwill recognized in connection with the BASE Acquisition is primarily attributable to (i) the ability to take advantage of BASE ’s existing mobile network to gain immediate access to potential customers and (ii) synergies that are expected to be achieved through the integration of BASE with Telenet . (b) As of February 11, 2016 , the weighted average useful life of BASE ’s mobile spectrum was approximately 11 years . (c) As of February 11, 2016 , the weighted average useful life of BASE ’s customer relationships was approximately seven years . (d) As of February 11, 2016 , the weighted average useful life of BASE ’s trademarks was approximately 20 years . (e) Excludes direct acquisition costs of $17.1 million , including $7.1 million incurred during 2016, which are included in impairment, restructuring and other operating items, net, in our consolidated statements of operations. 2015 Acquisition On June 3, 2015, pursuant to a stock 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 60.0% -owned by our company and 40.0% -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 opening balance sheet of Choice at the June 3, 2015 acquisition date is presented in the following table. The opening balance sheet presented below reflects our final purchase price allocation (in millions): Cash and cash equivalents $ 3.6 Other current assets 7.8 Property and equipment, net 79.8 Goodwill (a) 51.6 Intangible assets subject to amortization, net (b) 59.1 Cable television franchise rights 147.8 Other assets, net 0.3 Other accrued and current liabilities (13.2 ) Non-current deferred tax liabilities (60.4 ) 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) synergies that are expected to be achieved through the integration of Choice with Liberty Puerto Rico . (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 incurred through December 31, 2015, which are included in impairment, restructuring and other operating items, net, in our consolidated statements of operations. 2014 Acquisition On November 11, 2014 (the Ziggo Acquisition Date ), pursuant to a merger protocol (the Ziggo Merger Protocol ) with respect to an offer to acquire all of the shares of Ziggo Holding B.V. ( Ziggo ) that we did not already own (the Ziggo Offer ), we gained control of Ziggo through the acquisition of 136,603,794 additional Ziggo shares, which increased our ownership interest in Ziggo to 88.9% (the Ziggo Acquisition ). 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 ). Ziggo is a provider of video, broadband internet, fixed-line telephony and mobile services in the Netherlands. We acquired Ziggo in order to achieve certain financial, operational and strategic benefits through the integration of Ziggo with with our then-existing operations in the Netherlands and our other European operations. On December 31, 2016, our operations in the Netherlands were contributed to the Dutch JV , as defined and described in note 5 . Pursuant to the Ziggo Merger Protocol , Ziggo shareholders who tendered their Ziggo shares received an offer price of (i) 0.2282 Class A Old Liberty Global Shares , (ii) 0.5630 Class C Old Liberty Global Shares and (iii) €11.00 ( $13.71 at the applicable rates) in cash for each Ziggo share that they tendered. In connection with the completion of the Ziggo Acquisition and the Ziggo NCI Acquisition , we (a) issued an aggregate of 35,508,342 Class A and 87,603,842 Class C Old Liberty Global Shares and (b) paid aggregate cash consideration of €1,711.6 million ( $2,133.6 million at the applicable rates) to holders of Ziggo ordinary shares. On December 3, 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 ( $44.91 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. 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. For accounting purposes, the Ziggo Acquisition was treated as the acquisition of Ziggo by Liberty Global . In this regard, the equity and cash consideration paid to acquire Ziggo plus the fair value of our pre-existing investment in Ziggo on the Ziggo Acquisition Date is set forth below (in millions): Class A Old Liberty Global Shares (a) $ 1,448.7 Class C Old Liberty Global Shares (a) 3,457.1 Cash (b) 1,872.9 Fair value of pre-existing investment in Ziggo (c) 2,015.4 Total $ 8,794.1 _______________ (a) Represents the value assigned to the 31,172,985 Class A and 76,907,936 Class C Old Liberty Global Shares issued to Ziggo shareholders in connection with the Ziggo Acquisition through the Ziggo Acquisition Date . These amounts are based on (i) the exchange ratios specified by the Ziggo Merger Protocol , (ii) the applicable closing per share prices of Class A and Class C Old Liberty Global Shares and (iii) 136,603,794 ordinary shares of Ziggo tendered in the Ziggo Offer through the Ziggo Acquisition Date . (b) Represents the cash consideration paid in connection with the Ziggo Acquisition . (c) Represents the fair value of the 41,329,850 shares of Ziggo held by Liberty Global and its subsidiaries immediately prior to the Ziggo Acquisition . We have accounted for the Ziggo Acquisition using the acquisition method of accounting, whereby the total purchase price was allocated to the acquired identifiable net assets of Ziggo based on assessments of their respective fair values, and the excess of the purchase price over the fair values of these identifiable net assets was allocated to goodwill. A summary of the purchase price and the opening balance sheet for the Ziggo Acquisition as of the Ziggo Acquisition Date is presented in the following table. The opening balance sheet presented below reflects our final purchase price allocation (in millions): Cash and cash equivalents (a) $ 1,889.7 Other current assets 69.7 Property and equipment, net 2,714.9 Goodwill (b) 7,866.5 Intangible assets subject to amortization, net (c) 4,857.0 Other assets, net 382.8 Current portion of debt and capital lease obligations (604.0 ) Other accrued and current liabilities (461.8 ) Long-term debt and capital lease obligations (5,351.5 ) Other long-term liabilities (1,488.6 ) Noncontrolling interest (d) (1,080.6 ) Total purchase price (e) $ 8,794.1 _______________ (a) The Ziggo Acquisition resulted in $16.8 million of net cash acquired after deducting the cash consideration paid. (b) The goodwill recognized in connection with the Ziggo Acquisition was primarily attributable to (i) the ability to take advantage of Ziggo ’s existing advanced broadband communications network to gain immediate access to potential customers and (ii) synergies that were expected to be achieved through the integration of Ziggo with our then-existing operations in the Netherlands and our other European operations. (c) Amount primarily includes intangible assets related to customer relationships. As of the Ziggo Acquisition Date , the weighted average useful life of Ziggo ’s intangible assets was approximately ten years . (d) Represents the fair value of the noncontrolling interest in Ziggo as of the Ziggo Acquisition Date . (e) Excludes direct acquisition costs of $84.1 million incurred through December 31, 2014, which are included in impairment, restructuring and other operating items, net, in our consolidated statement of operations. We have accounted for the Ziggo NCI Acquisition as an equity transaction, with the carrying amount of the noncontrolling interest adjusted to reflect the change in ownership of Ziggo . The difference between the fair value of consideration paid and the amount by which the noncontrolling interest was adjusted has been recognized as additional paid-in capital in our consolidated statement of equity. The impact of the Ziggo NCI Acquisition is summarized in the following table (in millions): Reduction of noncontrolling interests $ 927.2 Additional paid-in capital 23.5 Fair value of consideration paid (a) $ 950.7 _______________ (a) Represents (i) the value assigned to the 4,335,357 Class A and 10,695,906 Class C Old Liberty Global Shares issued to Ziggo shareholders and (ii) cash consideration of €209.0 million ( $260.7 million at the applicable rates) paid to Ziggo shareholders, based on the 18,998,057 ordinary shares of Ziggo tendered in connection with the Ziggo NCI Acquisition . The cash consideration paid in the Ziggo Acquisition and the Ziggo NCI Acquisition was funded with a combination of debt and our existing liquidity. Pro Forma Information In pro forma tables presented below, 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 or loss and basic and diluted earnings or loss per share attributed to (i) Liberty Global Shares , (ii) LiLAC Shares and (iii) Old Liberty Global Shares only includes the results of operations for the periods during which these shares were outstanding. Accordingly, (a) our net earnings or loss attributed to Liberty Global Shares and LiLAC Shares relates to periods subsequent to July 1, 2015 and (b) our net loss attributed to Old Liberty Global Shares relates to periods prior to July 1, 2015. The following unaudited pro forma consolidated operating results give effect to (i) the CWC Acquisition , (ii) the BASE Acquisition and (iii) the Choice Acquisition , as if they had been completed as of January 1, 2015 .

Discontinued Operations and Disposal Groups [Abstract]
Dutch JV Transaction and Discontinued Operation	Dutch JV Transaction and Discontinued Operation Dutch JV Transaction On December 31, 2016, pursuant to a Contribution and Transfer Agreement with Vodafone Group plc ( Vodafone ) and one of its wholly-owned subsidiaries, we and Liberty Global Europe Holding B.V., our wholly-owned subsidiary, contributed Ziggo Group Holding and its subsidiaries (including Liberty Global Netherlands Content B.V., referred to herein as “ Ziggo Sport ”) to VodafoneZiggo Group Holding B.V., a newly-formed 50 : 50 joint venture (referred to herein as the “ Dutch JV ”). Ziggo Sport , which became a subsidiary of Ziggo Group Holding during the fourth quarter of 2016, operates premium sports channels in the Netherlands. The Dutch JV combined Ziggo Group Holding with Vodafone ’s mobile businesses in the Netherlands ( Vodafone NL ) to create a national unified communications provider in the Netherlands with complementary strengths across video, broadband, mobile and B2B services (the Dutch JV Transaction ). As a result of the Dutch JV Transaction , effective December 31, 2016 we no longer consolidate Ziggo Group Holding . For additional information regarding our investment in the Dutch JV , see note 6. On January 4, 2017, in connection with the completion of the Dutch JV Transaction , our company received cash of €2.2 billion ( $2.3 billion at the transaction date) comprising (i) our 50% share of the €2.8 billion ( $2.9 billion at the transaction date) of net proceeds from the various debt financing arrangements entered into by certain subsidiaries of Ziggo Group Holding during the third quarter of 2016, which proceeds were held in escrow through December 31, 2016, and (ii) an equalization payment from Vodafone of €802.9 million ( $840.8 million at the transaction date) that is subject to post-closing adjustments. Our right to receive this cash is reflected in our December 31, 2016 consolidated balance sheet as a current receivable from the Dutch JV . In connection with the Dutch JV Transaction , we recognized a pre-tax gain of $520.8 million , net of the recognition of a cumulative foreign currency translation loss of $714.5 million . This gain, which was calculated by deducting the carrying value of Ziggo Group Holding (including the related foreign currency translation loss) from the sum of (i) the fair value assigned to our 50% interest in the Dutch JV and (ii) the cash received pursuant to the equalization payment, includes $260.4 million related to the remeasurement of our retained investment in Ziggo Group Holding . For information regarding our approach to the valuation of our interest in the Dutch JV , see note 8 . Our consolidated statements of operations include aggregate earnings (loss) before income taxes attributable to Ziggo Group Holding and Ziggo Sport of ( $276.4 million ), ( $534.5 million ) and $270.2 million during 2016 , 2015 and 2014 , respectively. The December 31, 2016 carrying amounts of the major classes of assets and liabilities associated with Ziggo Group Holding , which was contributed into the Dutch JV , are summarized below (in millions): Assets: Cash and cash equivalents $ 6.1 Current restricted cash 3,144.0 Current assets other than cash 259.0 Property and equipment, net 3,201.2 Goodwill 7,637.2 Intangible assets subject to amortization, net 3,406.7 Other assets, net 578.8 Total assets $ 18,233.0 Liabilities: Current portion of debt and capital lease obligations $ 290.3 Other accrued and current liabilities 2,396.4 Long-term debt and capital lease obligations 11,812.8 Other long-term liabilities 991.7 Total liabilities $ 15,491.2 Discontinued Operation On January 31, 2014, we completed the sale of the Chellomedia Disposal Group to AMC Networks Inc. for €750.0 million ( $1,013.1 million at the applicable rate) in cash. Accordingly, the Chellomedia Disposal Group is reflected as a discontinued operation in our consolidated statements of operations and cash flows for 2014. The assets disposed of pursuant to the Chellomedia Transaction exclude Chellomedia ’s premium sports and film channels in the Netherlands. In connection with the sale of the Chellomedia Disposal Group , we recognized a pre-tax gain of $342.2 million . This pre-tax gain is net of a $64.0 million cumulative foreign currency translation loss, which was reclassified to net loss from accumulated other comprehensive earnings. The associated income tax expense of $9.5 million differs from the amount computed by applying the U.K. statutory income tax rate in effect at the time of 21.5% primarily due to the fact that (i) the transaction was not subject to taxation in the U.K. and (ii) most elements of the transaction were not subject to taxation in the Netherlands or the U.S. The net after-tax gain of $332.7 million is included in gain on disposal of discontinued operation, net of taxes, in our consolidated statement of operations. Certain of our broadband communications operations will continue to receive programming services from the Chellomedia Disposal Group through contracts that were negotiated as part of the disposal. As such, Liberty Global will have continuing cash outflows associated with the Chellomedia Disposal Group through at least 2017. However, our involvement as an ongoing customer of the Chellomedia Disposal Group does not disqualify discontinued operations classification because (i) the ongoing cash outflows are not considered significant to the Chellomedia Disposal Group and (ii) Liberty Global does not possess any rights within the ongoing contractual arrangements that would allow us to exert influence over the Chellomedia Disposal Group . The operating results of the Chellomedia Disposal Group are classified as a discontinued operation in our consolidated statement of operations and are summarized in the following table: Year ended December 31, 2014 (a) (b) in millions Revenue $ 26.6 Operating income $ 0.6 Earnings before income taxes and noncontrolling interests $ 0.9 Income tax expense $ (0.1 ) Earnings from discontinued operation attributable to Liberty Global shareholders, net of taxes $ 0.8 _______________ (a) Includes the operating results of the Chellomedia Disposal Group through January 31, 2014, the date the Chellomedia Disposal Group was sold. (b) Excludes the Chellomedia Disposal Group ’s intercompany revenue and expenses that are eliminated within Liberty Global

Investments	Investments The details of our investments are set forth below: December 31, Accounting Method 2016 2015 in millions Equity: Dutch JV (a) $ 4,186.6 $ — Other 142.7 247.4 Total — equity 4,329.3 247.4 Fair value: ITV — subject to re-use rights 1,015.4 1,624.1 Sumitomo 538.4 471.1 ITI Neovision 129.3 120.0 Lionsgate 128.6 162.0 Other 245.5 214.6 Total — fair value 2,057.2 2,591.8 Cost 97.2 0.4 Total $ 6,483.7 $ 2,839.6 _______________ (a) The 2016 amount includes a $1,054.7 million related-party loan from a subsidiary of Liberty Global to a subsidiary of the Dutch JV (the Dutch JV Loan Receivable ). The Dutch JV Loan Receivable bears interest at 5.55% and matures on January 16, 2027. Equity Method Investments Dutch JV . On December 31, 2016, we completed the Dutch JV Transaction . Each of Liberty Global and Vodafone (each a “ Shareholder ”) holds 50% of the issued share capital of the Dutch JV . The Shareholder s intend for the Dutch JV to be funded solely from its net cash flow from operations and third-party financing. We account for our 50% interest in the Dutch JV , which has been attributed to the Liberty Global Group , as an equity method investment. We consider the Dutch JV to be a related party. For additional information regarding the formation of the Dutch JV , see note 5 . In connection with the formation of the Dutch JV , the Shareholder s entered into a shareholders agreement (the Shareholders Agreement ). The Shareholders Agreement contains customary provisions for the governance of a 50 : 50 joint venture that result in Liberty Global and Vodafone having joint control over decision making with respect to the Dutch JV . The Shareholders Agreement also provides (i) for a dividend policy that requires the Dutch JV to distribute all unrestricted cash to the Shareholder s every two months (subject to the Dutch JV maintaining a minimum amount of cash and complying with the terms of its financing arrangements) and (ii) that the Dutch JV will be managed with a leverage ratio of between 4.5 and 5.0 times EBITDA (as calculated pursuant to its existing financing arrangements) with the Dutch JV undertaking periodic recapitalizations and/or refinancings accordingly. Each Shareholder has the right to initiate an initial public offering ( IPO ) of the Dutch JV after the third anniversary of the closing, with the opportunity for the other Shareholder to sell shares in the IPO on a pro rata basis. Subject to certain exceptions, the Shareholders Agreement prohibits transfers of interests in the Dutch JV to third parties until the fourth anniversary of the closing. After the fourth anniversary, each Shareholder will be able to initiate a sale of all of its interest in the Dutch JV to a third party and, under certain circumstances, initiate a sale of the entire Dutch JV ; subject, in each case, to a right of first offer in favor of the other Shareholder . Pursuant to an agreement entered into in connection with the closing of the Dutch JV (the Framework Agreement ), Liberty Global will provide certain services to the Dutch JV on a transitional or ongoing basis (collectively, the Dutch JV Services ). Pursuant to the terms of the Framework Agreement , the ongoing services will be provided for a period of four to six years depending on the type of service, while transitional services will be provided for a period of not less than 12 months after which both parties shall be entitled to terminate based on specified notice periods. The Dutch JV Services provided by Liberty Global will consist primarily of (i) technology and other services and (ii) capital-related expenditures for assets that will be used by or will otherwise benefit the Dutch JV . Liberty Global will charge both fixed and variable fees to the Dutch JV for the Dutch JV Services it provides during the term of the Framework Agreement , including estimated total fees of approximately €120 million ( $127 million ) during 2017 and minimum fees of approximately €100 million ( $105 million ) and €75 million ( $79 million ) during 2018 and 2019, respectively. The estimated fees for the Dutch JV Services during 2017 include approximately €23 million ( $24 million ) of costs that were related to goods and services that were centrally purchased by a Liberty Global corporate subsidiary and passed through to our Netherlands segment, which in turn reported these costs as operating expenses in 2016. Beginning in 2017, these costs will remain in Liberty Global 's operating expenses and will therefore offset a portion of the fees for the Dutch JV Services . The charges for the Dutch JV Services will be included in revenue in our consolidated statement of operations. The summarized financial condition of the Dutch JV as of December 31, 2016 is set forth below (in millions): Current assets $ 3,589.8 Long-term assets 20,751.0 Total assets $ 24,340.8 Current liabilities (a) $ 4,360.0 Long-term liabilities 14,041.8 Owners’ equity 5,939.0 Total liabilities and owners’ equity $ 24,340.8 _______________ (a) Amount includes a $21.0 million payable to Liberty Global for services provided to Ziggo Group Holding through December 31, 2016 . We have included the corresponding receivable amount in other current assets in our consolidated balance sheet. Fair Value Investments ITV . At December 31, 2016, we owned 398,515,510 shares of ITV plc ( ITV ), a commercial broadcaster in the U.K. Our ITV shares represented less than 10.0% of the total outstanding shares of ITV as of June 30, 2016, the most current publicly-available information. The aggregate purchase price paid to acquire our investment in ITV was financed through borrowings under secured borrowing agreements (the ITV Collar Loan ). 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 7 . Sumitomo . At December 31, 2016 and 2015 , we owned 45,652,043 shares of Sumitomo Corporation ( Sumitomo ) common stock. Our Sumitomo shares represented less than 5% of Sumitomo ’s outstanding common stock at September 30, 2016, the most current publicly-available information. These shares secure the Sumitomo Collar Loan and the Sumitomo Share Loan , each as defined and described in note 7 . ITI Neovision . At December 31, 2016 and 2015 , we owned a 17.0% interest in ITI Neovision S.A. ( ITI Neovision ) , a privately-held direct-to-home ( DTH ) operator in Poland. Lionsgate . On November 12, 2015, we acquired an aggregate of 5.0 million shares of Lions Gate Entertainment Corp. ( Lionsgate ) common stock, at a price of $39.02 per share, for an investment of $195.1 million . The aggregate purchase price of the Lionsgate shares was financed using working capital, including $70.9 million of cash received pursuant to a variable prepaid forward transaction with respect to 2.5 million Lionsgate shares (the Lionsgate Forward ). The Lionsgate Forward has economic characteristics similar to a collar plus a loan that is collateralized by a pledge of the aforementioned 2.5 million shares (the Lionsgate Loan ). Under the terms of the Lionsgate Forward , the counterparty does not have the right to re-use the pledged Lionsgate shares without permission from Liberty Global . On December 8, 2016, Lionsgate acquired Starz, LLC in a cash and stock transaction. Under the terms of the transaction, the existing share capital of Lionsgate was restructured such that each share of previously-existing Lionsgate common stock was converted into 0.5 newly-issued voting shares and 0.5 newly-issued non-voting shares. As a result, our original 5.0 million shares of Lionsgate were converted into 2.5 million shares of Lionsgate voting stock and 2.5 million shares of Lionsgate non-voting stock. The terms of the Lionsgate Forward were also amended to include both classes of shares. Our Lionsgate shares represented less than 5% of the total outstanding shares of Lionsgate as of November 1, 2016, the most current publicly available information. For additional information regarding the Lionsgate Forward , see note 7

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In general, we seek to enter into derivative instruments to protect against (i) increases in the interest rates on our variable-rate debt, (ii) foreign currency movements, particularly with respect to borrowings that are denominated in a currency other than the functional currency of the borrowing entity and (iii) decreases in the market prices of certain publicly traded securities that we own. In this regard, through our subsidiaries, we have entered into various derivative instruments to manage interest rate exposure and foreign currency exposure 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 ), Indian rupee ( INR ), the Jamaican dollar ( JMD ), the Philippine peso ( PHP ), the the Polish zloty ( PLN ) and the Romanian lei ( RON ).

(b) We consider credit risk in our fair value assessments. As of December 31, 2016 and 2015 , (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 $93.1 million and $64.0 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 $71.5 million and $86.5 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 $16.4 million , $9.3 million and $120.9 million during 2016 , 2015 and 2014 , respectively. These amounts are included in realized and unrealized gains on derivative instruments, net, in our consolidated statements of operations. For further information regarding our fair value measurements, see note 8 . (c) Our equity-related derivative instruments primarily include the fair value of (i) the ITV Collar (ii) the share collar with respect to the shares of Sumitomo held by our company (the Sumitomo Collar ), (iii) the Lionsgate Forward and (iv) at December 31, 2015, Virgin Media ’s conversion hedges with respect to Virgin Media ’s 6.50% convertible senior notes (the Virgin Media Capped Calls ). The fair values of the ITV Collar , the Sumitomo Collar and the Lionsgate Forward do not include credit risk valuation adjustments as we assume that any losses incurred by our company in the event of nonperformance by the respective counterparty would be, subject to relevant insolvency laws, fully offset against amounts we owe to such counterparty pursuant to the related secured borrowing arrangements. The details of our realized and unrealized gains on derivative instruments, net, are as follows: Year ended December 31, 2016 2015 2014 in millions Cross-currency and interest rate derivative contracts: Liberty Global Group $ 716.2 $ 855.7 $ 252.5 LiLAC Group (216.8 ) 217.0 41.1 Total cross-currency and interest rate derivative contracts 499.4 1,072.7 293.6 Equity-related derivative instruments - Liberty Global Group: ITV Collar 351.5 (222.6 ) (77.4 ) Sumitomo Collar (25.6 ) (20.3 ) (46.0 ) Lionsgate Forward 10.1 14.5 — Ziggo Collar (a) — — (113.3 ) Other 1.6 0.7 0.4 Total equity-related derivative instruments 337.6 (227.7 ) (236.3 ) Foreign currency forward and option contracts: Liberty Global Group 18.1 (9.0 ) 29.0 LiLAC Group (9.1 ) 10.3 2.6 Total foreign currency forward contracts 9.0 1.3 31.6 Other - Liberty Global Group (0.9 ) 0.9 (0.1 ) Total Liberty Global Group 1,071.0 619.9 45.1 Total LiLAC Group (225.9 ) 227.3 43.7 Total $ 845.1 $ 847.2 $ 88.8 _______________ (a) Upon completion of the Ziggo Acquisition , the Ziggo Collar (as defined and described below) was terminated.

We manage these credit risks through the evaluation and monitoring of the creditworthiness of, and concentration of risk with, the respective counterparties. In this regard, credit risk associated with our derivative instruments is spread across a relatively broad counterparty base of banks and financial institutions. With the exception of a limited number of instances where we have required a counterparty to post collateral, neither party has posted collateral under the derivative instruments of our subsidiary borrowing groups. At December 31, 2016 , our exposure to counterparty credit risk included derivative assets with an aggregate fair value of $2,424.6 million . Each of our subsidiary borrowing groups have entered into derivative instruments under master agreements with each counterparty that contain master netting arrangements that are applicable in the event of early termination by either party to such derivative instrument. The master netting arrangements under each of these master agreements are limited to the derivative instruments governed by the relevant master agreement within each individual borrowing group and are independent of similar arrangements of our other subsidiary borrowing groups. Under our derivative contracts, it is generally only the non-defaulting party that has a contractual option to exercise early termination rights upon the default of the other counterparty and to set off other liabilities against sums due upon such termination. However, in an insolvency of a derivative counterparty, under the laws of certain jurisdictions, the defaulting counterparty or its insolvency representatives may be able to compel the termination of one or more derivative contracts and trigger early termination payment liabilities payable by us, reflecting any mark-to-market value of the contracts for the counterparty. Alternatively, or in addition, the insolvency laws of certain jurisdictions may require the mandatory set off of amounts due under such derivative contracts against present and future liabilities owed to us under other contracts between us and the relevant counterparty. Accordingly, it is possible that we may be subject to obligations to make payments, or may have present or future liabilities owed to us partially or fully discharged by set off as a result of such obligations, in the event of the insolvency of a derivative counterparty, even though it is the counterparty that is in default and not us. To the extent that we are required to make such payments, our ability to do so will depend on our liquidity and capital resources at the time. In an insolvency of a defaulting counterparty, we will be an unsecured creditor in respect of any amount owed to us by the defaulting counterparty, except to the extent of the value of any collateral we have obtained from that counterparty. In addition, where a counterparty is in financial difficulty, under the laws of certain jurisdictions, the relevant regulators may be able to (i) compel the termination of one or more derivative instruments, determine the settlement amount and/or compel, without any payment, the partial or full discharge of liabilities arising from such early termination that are payable by the relevant counterparty or (ii) transfer the derivative instruments to an alternative counterparty. 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 December 31, 2016 , we present a single date that represents the applicable final maturity date. For derivative instruments that become effective subsequent to December 31, 2016 , we present a range of dates that represents the period covered by the applicable derivative instruments.

Equity-related Derivative Instruments ITV Collar and Secured Borrowing . The ITV Collar comprises (i) purchased put options exercisable by Liberty Global Incorporated Limited ( Liberty Global Limited ), our wholly-owned subsidiary, and (ii) written call options exercisable by the counterparty. The ITV Collar effectively hedges the value of our investment in ITV shares from losses due to market price decreases below the put option price while retaining a portion of the gains from market price increases up to the call option price. The fair value of the ITV Collar as of December 31, 2016 was a net asset of $311.9 million , which is classified as non-current in our consolidated balance sheet. For additional information regarding our investment in ITV , see note 6 . The ITV Collar has settlement dates ranging from October 2017 through May 2019. The ITV Collar and related agreements also provide Liberty Global Limited with the ability to effectively finance the purchase of its ITV shares pursuant to the ITV Collar Loan . In July 2014 and in connection with our initial investment in ITV , Liberty Global Limited borrowed £446.9 million ( $764.5 million at the transaction date) under the ITV Collar Loan . In July 2015 and in connection with an additional investment in ITV (the Additional ITV Investment ), Liberty Global Limited (i) modified the purchased put option and written call option strike prices within the ITV Collar and (ii) increased its borrowings under the ITV Collar Loan , resulting in net cash received of $92.0 million . The amount received in connection with the Additional ITV Investment includes $77.5 million of cash borrowings under the ITV Collar Loan that were not required to fund the Additional ITV Investment and $14.5 million related to the ITV Collar Loan 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 . At December 31, 2016 , borrowings under the ITV Collar Loan were secured by all 398,515,510 of our ITV shares, which have been placed into a custody account. The ITV Collar Loan was issued at a discount with a zero coupon rate and has an average implied yield of 139 basis points ( 1.39% ). The ITV Collar Loan , which has maturity dates consistent with the ITV Collar and contains no financial covenants, provides for customary representations and warranties, events of default and certain adjustment and termination events. Under the terms of the ITV Collar , the counterparty has the right to re-use the pledged ITV shares held in the custody account, but we have the right to recall the shares that are re-used by the counterparty subject to certain costs. In addition, the counterparty retains dividends on the ITV shares that the counterparty would need to borrow from the custody account to hedge its exposure under the ITV Collar (an estimated 390 million shares at December 31, 2016 ). Sumitomo Collar and Secured Borrowing. The Sumitomo Collar comprises purchased put options exercisable by Liberty Programming Japan LLC ( Liberty Programming Japan ), our wholly-owned subsidiary, and written call options exercisable by the counterparty with respect to a portion of the Sumitomo shares owned by Liberty Programming Japan . At December 31, 2016 , the Sumitomo Collar effectively hedges the value of 27,391,305 , or 60% , of our Sumitomo shares from losses due to market price decreases below the put strike price. The Sumitomo Collar provides for a projected gross cash ordinary dividend to be paid per Sumitomo share during the term of the Sumitomo Collar . If the actual dividend paid does not exactly match the projected dividend, then an adjustment amount shall be payable between the parties to the Sumitomo Collar depending on the dividend actually paid by Sumitomo . The Sumitomo Collar may, at the option of Liberty Programming Japan , be settled in Sumitomo shares or in cash. The Sumitomo Collar also includes a purchased fair value put option, which effectively provides Liberty Programming Japan with the ability to sell the Sumitomo shares when the market price is trading between the put and call strike prices. The fair value of the Sumitomo Collar as of December 31, 2016 was a net asset of $179.9 million , which is classified as non-current in our consolidated balance sheet. The Sumitomo Collar and related agreements also provide Liberty Programming Japan with the ability to borrow funds on a secured basis. Borrowings under these agreements (the Sumitomo Collar Loan ) are secured by 60% of our Sumitomo shares and bear interest at 1.883% . The pledge arrangement entered into by Liberty Programming Japan provides that Liberty Programming Japan will be able to exercise all voting and consensual rights and, subject to the terms of the Sumitomo Collar , receive dividends on the Sumitomo shares. Borrowings under the Sumitomo Collar Loan are included in our long-term debt and capital lease obligations in our consolidated balance sheets. For additional information, see note 10. The Sumitomo Collar and the Sumitomo Collar Loan each mature in five equal semi-annual installments, the first and second of which became due on May 22, 2016 and November 22, 2016. In May and November 2016, Liberty Programming Japan borrowed shares of Sumitomo pursuant to a securities lending arrangement (the Sumitomo Share Loan ) to settle the first and second installments due on the Sumitomo Collar Loan . The Sumitomo Share Loan , which we have elected to account for at fair value, bears interest at 1.10% and matures on the fifth anniversary of the respective borrowing dates. The Sumitomo Share Loan , together with the Sumitomo Collar, effectively hedge 100% of our Sumitomo shares from losses due to market price decreases. The Sumitomo Share Loan is secured by 40% of our Sumitomo shares. These shares were released from the Sumitomo Collar Loan after settlement of the first and second installments. Lionsgate Forward and Secured Borrowing. The Lionsgate Forward has the economic equivalent of (i) purchased put options exercisable by Liberty Global Limited and (ii) written call options exercisable by the counterparty. The Lionsgate Forward effectively hedges the value of 2.5 million of our Lionsgate shares from losses due to market price decreases below the put option price while retaining a portion of the gains from market price increases up to the call option price. The fair value of the Lionsgate Forward as of December 31, 2016 was a net asset of $23.6 million , which is classified as non-current in our consolidated balance sheet. For additional information regarding our investment in Lionsgate , see note 6 . The Lionsgate Forward has settlement dates ranging from July 2019 through March 2022. The Lionsgate Forward and related agreements also provide Liberty Global Limited with the ability to effectively finance a portion of the purchase of its Lionsgate shares pursuant to the Lionsgate Loan . In November 2015, Liberty Global Limited borrowed $69.7 million under the Lionsgate Loan . At December 31, 2016 , borrowings under the Lionsgate Loan were secured by 2.5 million of our Lionsgate shares, which have been placed into a custody account. The Lionsgate Loan was issued at a discount with a zero coupon rate and an average implied yield of 350 basis points ( 3.5% ). The Lionsgate Loan , which has maturity dates consistent with the Lionsgate Forward and contains no financial covenants, provides for customary representations and warranties, events of default and certain adjustment and termination events. Under the terms of the Lionsgate Forward , the counterparty does not have the right to re-use the pledged Lionsgate shares without permission from Liberty Global . In addition, Liberty Global Limited is obligated to share with the counterparty the economic benefit of any dividends paid during the term of the pledge based on a formula that takes into account a theoretical hedging position by the counterparty under the Lionsgate Forward (an estimated 1.7 million shares at December 31, 2016 ). Ziggo Collar and Secured Borrowing . During 2013, Liberty Global Limited entered into a share collar (the Ziggo Collar ) and secured borrowing arrangement (the Ziggo Collar Loan ) with respect to the then owned 24,957,000 Ziggo shares. The Ziggo Collar was comprised of (i) purchased put options exercisable by Liberty Global Limited and (ii) sold call options exercisable by the counterparty. Prior to the Ziggo Acquisition , the Ziggo Collar effectively hedged the value of a portion of our investment in Ziggo shares from significant losses due to market price decreases below the put option price while retaining a portion of the gains from market price increases up to the call option price. The Ziggo Collar and related agreements also provided Liberty Global Limited with the ability to effectively finance the purchase of certain of its Ziggo shares pursuant to the Ziggo Collar Loan . Upon completion of the Ziggo Acquisition (see note 4 ), the Ziggo Collar was terminated and the Ziggo Collar Loan was settled. Virgin Media Capped Calls . During 2010, Virgin Media entered into the Virgin Media Capped Calls in order to offset a portion of the dilutive effects associated with the exchange of certain exchangeable notes of Virgin Media . During 2013, and in connection with the exchange of certain exchangeable notes of Virgin Media , we settled 93.8% of the notional amount of the Virgin Media Capped Calls . During 2016, the remaining outstanding notional amount of the Virgin Media Capped Calls was settled for cash proceeds of $36.2 million .

Fair Value Measurements

Fair Value Measurements	12 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, (ii) our derivative instruments, (iii) certain instruments that we classify as debt and (iv) the Sumitomo Share Loan . The reported fair values of these investments and instruments as of December 31, 2016 likely will not represent the value that will be paid or received upon the ultimate settlement or disposition of these assets and liabilities. In the case of the investments that we account for using the fair value method, the values we realize upon disposition will be dependent upon, among other factors, market conditions and the forecasted financial performance of the investees at the time of any such disposition. With respect to our derivative and certain debt instruments, we expect that the values realized generally will be based on market conditions at the time of settlement, which may occur at the maturity of the derivative instrument or at the time of the repayment or refinancing of the underlying debt instrument. U.S. GAAP provides for a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. We record transfers of assets or liabilities into or out of Levels 1, 2 or 3 at the beginning of the quarter during which the transfer occurred. During 2016 , 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 , Sumitomo and Lionsgate , 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. During the second quarter of 2016, we entered into the Sumitomo Share Loan . As the primary input for this recurring fair value measurement is the quoted market price of the borrowed shares of Sumitomo , we believe this valuation falls under Level 1 of the fair value hierarchy. 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 over the terms of the derivative instruments, we have determined that these valuations fall under Level 3 of the fair value hierarchy. At December 31, 2016 , the valuations of the ITV Collar , the Sumitomo Collar and the Lionsgate Forward were not significantly impacted by forecasted volatilities. In order to manage our interest rate and foreign currency exchange risk, we have entered into (i) various derivative instruments and (ii) certain instruments that we classify as debt, as further described in notes 7 and 10 , respectively. The recurring fair value measurements of these instruments are determined using discounted cash flow models. With the exception of the inputs for the U.S. dollar to Jamaican dollar cross-currency swaps (the Sable Currency Swap ) held by Sable , 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 instruments. This observable data mostly includes 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 these instruments. As we would not expect changes in our or our counterparties’ credit spreads to have a significant impact on the valuations of these instruments, we have determined that these valuations (other than the Sable Currency Swap valuation) fall under Level 2 of the fair value hierarchy. Due to the lack of Level 2 inputs for the Sable Currency Swap valuation, we believe this valuation falls under Level 3 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 7 . Fair value measurements are also used in connection with nonrecurring valuations performed in connection with impairment assessments, acquisition accounting and the accounting for our initial investment in the Dutch JV . These nonrecurring valuations include the valuation of reporting units, customer relationship and other intangible assets, property and equipment, the implied value of goodwill and the valuation of our initial investment in the Dutch JV . The valuation of private reporting units and our initial investment in the Dutch JV is based at least in part on discounted cash flow analyses. With the exception of certain inputs for our weighted average cost of capital and discount rate calculations that are derived from pricing services, the inputs used in our discounted cash flow analyses, such as forecasts of future cash flows, are based on our assumptions. The valuation of customer relationships is primarily based on an excess earnings methodology, which is a form of a discounted cash flow analysis. The excess earnings methodology requires us to estimate the specific cash flows expected from the customer relationship, considering such factors as estimated customer life, the revenue expected to be generated over the life of the customer relationship, contributory asset charges and other factors. Tangible assets are typically valued using a replacement or reproduction cost approach, considering factors such as current prices of the same or similar equipment, the age of the equipment and economic obsolescence. The implied value of goodwill is determined by allocating the fair value of a reporting unit to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination, with the residual amount allocated to goodwill. All of our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy. During 2016 , 2015 and 2014 , we performed nonrecurring valuations for the purpose of determining (i) the acquisition accounting for the CWC Acquisition , the BASE Acquisition , the Choice Acquisition and the Ziggo Acquisition and (ii) the valuation of our initial investment in the Dutch JV . The weighted average discount rates used in the preliminary valuation of the customer relationships acquired as a result of the CWC Acquisition ranged from 8.8% to 12.8% . None of the valuations for the BASE Acquisition had a significant impact on our consolidated balance sheet. We used discount rates of (a) 11.75% and 12.25% for our respective valuations of the customer relationships and cable television franchise rights acquired as a result of the Choice Acquisition and (b) 8.50% for our valuation of the customer relationships acquired as a result of the the Ziggo Acquisition . The weighted average cost of capital used to value our initial investment in the Dutch JV was 7.0% . For information regarding our acquisitions, see note 4 . For information regarding our investment in the Dutch JV , see note 6 .

At December 31, 2016 and 2015 , the amount of property and equipment, net, recorded under capital leases was $1,061.5 million and $1,281.7 million , respectively. Most of these amounts relate to assets included in our distribution systems category. Depreciation of assets under capital leases is included in depreciation and amortization in our consolidated statements of operations. During 2016 , 2015 and 2014 , we recorded non-cash increases to our property and equipment related to vendor financing arrangements of $2,064.2 million , $1,481.5 million and $ 975.3 million , respectively, which exclude related VAT of $277.9 million , $189.3 million and $114.9 million , respectively, that was also financed by our vendors under these arrangements. In addition, during 2016 , 2015 and 2014 , we recorded non-cash increases to our property and equipment related to assets acquired under capital leases of $111.6 million , $106.1 million and $127.2 million , respectively. Most of our property and equipment is pledged as security under our various debt instruments. For additional information, see note 10 . During the fourth quarter of 2014, we recorded an impairment charge of $68.7 million to reduce the carrying amount of certain of Ziggo ’s internal-use software assets to zero following our determination that these assets would have no future service potential for our combined operations in the Netherlands.

For additional information, see note 5 . (b) Represents enterprise-level goodwill that is allocated to our Puerto Rico segment for purposes of our impairment tests. Based on the results of our October 1, 2016 goodwill impairment test, a hypothetical decline of 20% or more in the fair value of any of CWC’s reporting units could result in the need to record a goodwill impairment charge. At December 31, 2016, the aggregate goodwill associated with the CWC reporting units was $5.5 billion . If, among other factors, (i) the equity values of the LiLAC Group were to remain depressed or decline further or (ii) the adverse impacts of economic, competitive, regulatory or other factors were to cause our results of operations or cash flows to be worse than anticipated, we could conclude in future periods that impairment charges are required in order to reduce the carrying values of our goodwill and, to a lesser extent, other long-lived assets. Any such impairment charges could be significant. At December 31, 2016 and 2015 and based on exchange rates as of those dates, our accumulated goodwill impairments were $180.4 million and $186.8 million , respectively. These amounts represent accumulated impairments related to our broadband communications operations in Romania, which operations are included within the European Division ’s Central and Eastern Europe segment.

The original contracts were concluded in 2000 and 2001 and have indefinite terms, subject to certain mandatory statutory termination rights for either party after a term of 30 years . With certain limited exceptions, the lessor generally is not entitled to terminate these leases. For information regarding litigation involving these duct network lease agreements, see note 17 . (2) At December 31, 2016 and 2015 , Telenet ’s capital lease obligations included €341.2 million ( $359.9 million ) and €329.3 million ( $347.3 million ), respectively, associated with Telenet ’s lease of the broadband communications network of the four associations of municipalities in Belgium, which we refer to as the pure intercommunalues or the “ PICs .” All capital expenditures associated with the PICs network are initiated by Telenet , but are executed and financed by the PICs through additions to this lease that are repaid over a 15 -year term. These amounts do not include Telenet ’s commitment related to certain operating costs associated with the PICs network. For additional information regarding this commitment, see note 17 . General Information At December 31, 2016 , most of our outstanding debt had been incurred by one of our seven primary "borrowing groups." These borrowing groups include the respective restricted parent and subsidiary entities within Virgin Media , Unitymedia , UPC Holding , Telenet , CWC , VTR Finance and Liberty Puerto Rico . Credit Facilities. Each of our borrowing groups has entered into one or more credit facility agreements with certain financial institutions. Each of these credit facilities contain certain covenants, the more notable of which are as follows: • Our credit facilities contain certain consolidated net leverage ratios, as specified in the relevant credit facility, which are required to be complied with on an incurrence and/or maintenance basis; • Our credit facilities contain certain restrictions which, among other things, restrict the ability of the members of the relevant borrowing group to (i) incur or guarantee certain financial indebtedness, (ii) make certain disposals and acquisitions, (iii) create certain security interests over their assets, in each case, subject to certain customary and agreed exceptions and (iv) make certain restricted payments to their direct and/or indirect parent companies (and indirectly to Liberty Global ) through dividends, loans or other distributions, subject to compliance with applicable covenants; • Our credit facilities require that certain members of the relevant borrowing group guarantee the payment of all sums payable under the relevant credit facility and such group members are required to grant first-ranking security over their shares or, in certain borrowing groups, over substantially all of their assets to secure the payment of all sums payable thereunder; • In addition to certain mandatory prepayment events, the instructing group of lenders under the relevant credit facility may cancel the commitments thereunder and declare the loans thereunder due and payable after the applicable notice period following the occurrence of a change of control (as specified in the relevant credit facility); • Our credit facilities contain certain customary events of default, the occurrence of which, subject to certain exceptions and materiality qualifications, would allow the instructing group of lenders to (i) cancel the total commitments, (ii) accelerate all outstanding loans and terminate their commitments thereunder and/or (iii) declare that all or part of the loans be payable on demand; • Our credit facilities require members of the relevant borrowing group to observe certain affirmative and negative undertakings and covenants, which are subject to certain materiality qualifications and other customary and agreed exceptions; and • In addition to customary default provisions, our credit facilities generally include certain cross-default and cross-acceleration provisions with respect to other indebtedness of members of the relevant borrowing group, subject to agreed minimum thresholds and other customary and agreed exceptions. Senior and Senior Secured Notes. Certain of our borrowing groups have issued senior and/or senior secured notes. In general, our senior and senior secured notes (i) are senior obligations of each respective issuer within the relevant borrowing group that rank equally with all of the existing and future senior debt of such issuer and are senior to all existing and future subordinated debt of each respective issuer within the relevant borrowing group, (ii) contain, in most instances, certain guarantees from other members of the relevant borrowing group (as specified in the applicable indenture) and (iii) with respect to our senior secured notes, are secured by certain pledges or liens over the assets and/or shares of certain members of the relevant borrowing group. In addition, the indentures governing our senior and senior secured notes contain certain covenants, the more notable of which are as follows: • Our notes contain certain customary incurrence-based covenants. In addition, our 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 the issuer or certain subsidiaries, over agreed minimum thresholds (as specified under the applicable indenture), is an event of default under the respective notes; • Our notes contain certain restrictions that, among other things, restrict the ability of the members of the relevant borrowing group to (i) incur or guarantee certain financial indebtedness, (ii) make certain disposals and acquisitions, (iii) create certain security interests over their assets, in each case, subject to certain customary and agreed exceptions and (iv) make certain restricted payments to its direct and/or indirect parent companies (and indirectly to Liberty Global ) through dividends, loans or other distributions, subject to compliance with applicable covenants; • If the relevant issuer or certain of its subsidiaries (as specified in the applicable indenture) sell certain assets, such issuer must offer to repurchase the applicable notes at par, or if a change of control (as specified in the applicable indenture) occurs, such issuer must offer to repurchase all of the relevant notes at a redemption price of 101% ; and • Our senior secured notes contain certain early redemption provisions including the ability to, during each 12 -month period commencing on the issue date for such notes until the applicable call date, redeem up to 10% of the principal amount of the notes to be redeemed at a redemption price equal to 103% of the principal amount of the notes to be redeemed plus accrued and unpaid interest. SPE Notes . From time to time, we create special purpose financing entities ( SPEs ), which are 100% owned by third parties, for the primary purpose of facilitating the offering of senior and senior secured notes, which we collectively refer to as the " SPE Notes ." In this regard, SPE Notes have been issued, and are outstanding at December 31, 2016 , by UPCB Finance IV Limited ( UPCB Finance IV , the UPCB SPE ), and Telenet Finance V Luxembourg S.C.A. ( Telenet Finance V ) and Telenet Finance VI Luxembourg S.C.A. ( Telenet Finance VI ), collectively the " Telenet SPE s ." The SPEs used the proceeds from the issuance of SPE Notes to fund term loan facilities under their respective borrowing group (as further described below), each a “ Funded Facility ” and collectively the “ Funded Facilities .” Each SPE is dependent on payments from the relevant borrower under the applicable Funded Facility in order to service its payment obligations under each respective SPE Note . Although none of the respective borrowing entities under the Funded Facilities have any equity or voting interest in any of the relevant SPEs , each of the Funded Facility term loans creates a variable interest in the respective SPE for which the relevant borrowing entity is the primary beneficiary. As such, each borrowing entity under the relevant Funded Facility and its parent entities, including Liberty Global , are required to consolidate the relevant SPEs . As a result, the amounts outstanding under the Funded Facilities are eliminated in the respective borrowing group’s and Liberty Global ’s consolidated financial statements. Pursuant to the respective indentures for the SPE Notes (the SPE Indentures ) and the respective accession agreements for the Funded Facilities , the call provisions, maturity and applicable interest rate for each Funded Facility are the same as those of the related SPE Notes . The SPEs , as lenders under the relevant credit facility for each respective borrowing group, are treated the same as the other lenders under the respective credit facility, with benefits, rights and protections similar to those afforded to the other lenders. Through the covenants in the applicable SPE Indentures and the applicable security interests over (i) all of the issued shares of the relevant SPE and (ii) the relevant SPE ’s rights under the applicable Funded Facility granted to secure the relevant SPE ’s obligations under the relevant SPE Notes , the holders of the SPE Notes are provided indirectly with the benefits, rights, protections and covenants granted to the SPEs as lenders under the respective credit facility. The SPEs are prohibited from incurring any additional indebtedness, subject to certain exceptions under the SPE Indentures .

The components of our earnings (loss) from continuing operations before income taxes are as follows: Year ended December 31, 2016 2015 2014 in millions U.K. $ 930.7 $ 778.1 $ 585.7 U.S. (848.5 ) (924.5 ) (1,105.6 ) Switzerland 274.6 395.3 326.1 The Netherlands 127.4 — (1,353.3 ) — (644.5 ) Germany (49.3 ) (5.1 ) (294.7 ) Chile 47.4 182.3 43.1 Panama 19.4 — — Belgium 13.7 — 175.4 — 21.5 Other 34.0 67.2 12.5 Total $ 549.4 $ (684.6 ) $ (1,055.9 ) Income tax benefit (expense) consists of: Current Deferred Total in millions Year ended December 31, 2016: The Netherlands $ (0.4 ) $ 1,315.3 $ 1,314.9 U.S. (a) 146.9 88.3 235.2 Chile (134.3 ) (11.2 ) (145.5 ) Belgium (105.0 ) 57.0 (48.0 ) Switzerland (48.5 ) 5.3 (43.2 ) Germany (77.9 ) 41.0 (36.9 ) Panama (18.6 ) 14.1 (4.5 ) U.K. (15.3 ) 17.0 1.7 Other (49.0 ) (6.8 ) (55.8 ) Total $ (302.1 ) $ 1,520.0 $ 1,217.9 Year ended December 31, 2015: U.K $ (0.9 ) $ (208.5 ) $ (209.4 ) The Netherlands 2.5 159.0 161.5 Belgium (125.4 ) 11.1 (114.3 ) Switzerland (63.2 ) (14.7 ) (77.9 ) Chile (57.4 ) 13.5 (43.9 ) Germany (66.7 ) 24.3 (42.4 ) U.S. (a) (81.2 ) 58.7 (22.5 ) Other (22.7 ) 6.7 (16.0 ) Total $ (415.0 ) $ 50.1 $ (364.9 ) Year ended December 31, 2014: Continuing operations: U.K. $ (2.1 ) $ 113.4 $ 111.3 U.S. (a) (22.5 ) 129.6 107.1 Belgium (138.7 ) 31.7 (107.0 ) Switzerland (76.8 ) 3.1 (73.7 ) The Netherlands 11.1 42.5 53.6 Germany (22.6 ) 37.0 14.4 Chile 17.1 (24.1 ) (7.0 ) Other (41.1 ) 17.4 (23.7 ) Total — continuing operations $ (275.6 ) $ 350.6 $ 75.0 Discontinued operation $ — $ (0.1 ) $ (0.1 ) _______________ (a) Includes federal and state income taxes. Our U.S. state income taxes were not material during any of the years presented. 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: Year ended December 31, 2016 2015 2014 in millions Computed “expected” tax benefit (expense) (a) $ (109.9 ) $ 136.9 $ 221.7 Change in valuation allowances (b): Benefit 1,149.1 6.8 11.9 Expense (260.4 ) (508.3 ) (373.1 ) Recognition of previously unrecognized tax benefits 212.5 44.4 29.5 Non-deductible or non-taxable foreign currency exchange results (b): Benefit 228.0 53.2 71.9 Expense (34.3 ) (5.1 ) (16.3 ) Tax effect of intercompany financing 173.7 154.9 166.9 Non-deductible or non-taxable interest and other expenses (b): Expense (234.9 ) (106.6 ) (236.5 ) Benefit 63.8 48.1 58.0 Enacted tax law and rate changes (c) (162.2 ) (280.5 ) 23.9 International rate differences (b) (d): Benefit 138.1 200.8 266.4 Expense (43.0 ) (52.7 ) (27.6 ) Basis and other differences in the treatment of items associated with investments in subsidiaries and affiliates (b): Benefit 173.6 3.3 32.6 Expense (110.8 ) (96.9 ) (168.0 ) Other, net 34.6 36.8 13.7 Total income tax benefit (expense) $ 1,217.9 $ (364.9 ) $ 75.0 _______________ (a) The statutory or “expected” tax rates are the U.K. rates of 20.0% for 2016 and 2015 and 21.0% for 2014 . (b) Country jurisdictions giving rise to income tax benefits are grouped together and shown separately from country jurisdictions giving rise to income tax expenses. (c) During 2015, the U.K. enacted legislation that will change the corporate income tax rate from the current rate of 20.0% to 19.0% in April 2017 and 18.0% in April 2020. Substantially all of the impact of these rate changes on our deferred tax balances was recorded in the fourth quarter of 2015 when the change in law was enacted. During the third quarter of 2016, the U.K. enacted legislation that will further reduce the corporate income tax rate in April 2020 from 18.0% to 17.0% . Substantially all of the impact of this rate change on our deferred tax balances was recorded during the third quarter of 2016. (d) Amounts reflect adjustments (either a benefit or expense) to the “expected” tax benefit (expense) for statutory rates in jurisdictions in which we operate outside of the U.K. The components of our deferred tax assets are as follows: December 31, 2016 2015 in millions Deferred tax assets (a) $ 3,024.7 $ 2,342.9 Deferred tax liabilities (a) (1,307.8 ) (1,785.7 ) Net deferred tax asset $ 1,716.9 $ 557.2 _______________ (a) Our deferred tax assets and liabilities are included in other assets, net and other long-term liabilities, respectively, in our consolidated balance sheets. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are presented below: December 31, 2016 2015 in millions Deferred tax assets: Net operating loss and other carryforwards $ 6,598.0 $ 5,873.2 Property and equipment, net 2,028.9 2,583.1 Debt 1,626.3 1,611.7 Intangible assets 99.5 112.4 Derivative instruments 68.3 173.1 Other future deductible amounts 399.6 272.5 Deferred tax assets 10,820.6 10,626.0 Valuation allowance (6,015.4 ) (6,395.6 ) Deferred tax assets, net of valuation allowance 4,805.2 4,230.4 Deferred tax liabilities: Property and equipment, net (1,076.9 ) (1,053.4 ) Intangible assets (901.6 ) (1,826.5 ) Investments (including consolidated partnerships) (485.9 ) (374.5 ) Derivative instruments (175.5 ) (280.7 ) Other future taxable amounts (448.4 ) (138.1 ) Deferred tax liabilities (3,088.3 ) (3,673.2 ) Net deferred tax asset $ 1,716.9 $ 557.2 Our deferred income tax valuation allowance decreased $380.2 million in 2016 . This decrease reflects the net effect of (i) business acquisitions, (ii) the net tax benefit related to our continuing operations of $888.7 million , including a tax benefit of $1.1 billion recognized in the Netherlands upon the release of valuation allowances in the fourth quarter of 2016, (iii) foreign currency translation adjustments, (iv) the effect of enacted tax law and rate changes and (v) other individually insignificant items. The release of valuation allowances in the Netherlands is attributable to a significant improvement in our forecast of taxable income in the Netherlands, due to, among other factors, the impact of contributing Ziggo Group Holding to the Dutch JV on December 31, 2016, as further described in note 5. Virgin Media had property and equipment on which future U.K. tax deductions can be claimed of $17.9 billion and $21.0 billion at December 31, 2016 and 2015 , respectively. The maximum amount of these “capital allowances” that can be claimed in any one year is 18% of the remaining balance, after additions, disposals and prior claims. The tax effects of the excess of these capital allowances over the related financial reporting bases are included in the 2016 and 2015 deferred tax assets related to property and equipment, net, in the above table. At December 31, 2016 , our unrecognized excess tax benefits aggregated $139.0 million . These excess tax benefits, which represent tax deductions in excess of the financial reporting expense for share-based compensation, have not been recognized for financial reporting purposes as these tax benefits have not been realized as a reduction of income taxes payable. The tax effects of these unrecognized excess tax benefits are not included in the above table. For additional information regarding the adoption of ASU 2016-09, which will impact the accounting for unrecognized excess tax benefits beginning January 1, 2017, see note 2. The significant components of our tax loss carryforwards and related tax assets at December 31, 2016 are as follows: Country Tax loss carryforward Related tax asset Expiration date in millions U.K.: Amount attributable to capital losses $ 20,335.9 $ 3,457.1 Indefinite Amount attributable to net operating losses 2,563.4 435.8 Indefinite The Netherlands 4,108.7 1,027.2 2017-2025 Germany 1,608.1 259.5 Indefinite U.S. 1,268.0 320.1 2019-2036 Luxembourg 1,124.1 292.4 Indefinite Belgium 894.2 303.9 Indefinite Barbados 817.9 52.4 2017 - 2023 Ireland 601.9 75.2 Indefinite France 505.4 146.2 Indefinite Jamaica 449.7 149.9 Indefinite Hungary 166.8 15.0 2020-2025 Other 264.9 63.3 Various Total $ 34,709.0 $ 6,598.0 Our tax loss carryforwards within each jurisdiction combine all companies’ tax losses (both capital and ordinary losses) in that jurisdiction, however, certain tax jurisdictions limit the ability to offset taxable income of a separate company or different tax group with the tax losses associated with another separate company or group. Further, tax jurisdictions restrict the type of taxable income that the above losses are able to offset. The majority of the tax losses shown in the above table are not expected to be realized, including certain losses that are limited in use due to change in control or same business tests. We have taxable outside basis differences on certain investments in non- U.S. subsidiaries. We intend to indefinitely reinvest earnings from these non- U.S. operations. At December 31, 2016 , income and withholding taxes for which a net deferred tax liability might otherwise be required have not been provided on an estimated $6.9 billion of cumulative temporary differences (including, for this purpose, any difference between the aggregate tax basis in stock of a consolidated subsidiary and the corresponding amount of the subsidiary’s net equity, including cumulative translation adjustments, determined for financial reporting purposes) on non- U.S. entities. The determination of the additional withholding tax that would arise upon a reversal of these temporary differences is impractical to estimate as it is subject to offset by available foreign tax credits and subject to certain limitations. In general, a U.K. or U.S. corporation may claim a foreign tax credit against its income tax expense for foreign income taxes paid or accrued. A U.S. corporation may also claim a credit for foreign income taxes paid or accrued on the earnings of a foreign corporation paid to the U.S. corporation as a dividend. Our ability to claim a foreign tax credit for dividends received from our foreign subsidiaries or foreign taxes paid or accrued is subject to various significant limitations under U.S. tax laws, including a limited carry back and carry forward period. Some of our operating companies are located in countries with which the U.K. or U.S. does not have income tax treaties. Because we lack treaty protection in these countries, we may be subject to high rates of withholding taxes on distributions and other payments from these operating companies and may be subject to double taxation on our income. Limitations on the ability to claim a foreign tax credit, lack of treaty protection in some countries and the inability to offset losses in one jurisdiction against income earned in another jurisdiction could result in a high effective tax rate on our earnings. Since a significant portion of our revenue is generated outside of the U.K. and substantially all of our revenue is generated outside the U.S. , including in jurisdictions that do not have tax treaties with the U.K. or U.S. , these risks are greater for us than for companies that generate most of their revenue in the U.K. or U.S. or in jurisdictions that have these treaties. Through our subsidiaries, we maintain a presence in many countries. Many of these countries maintain highly complex tax regimes that differ significantly from the system of income taxation used in the U.K. and the U.S. We have accounted for the effect of these taxes based on what we believe is reasonably expected to apply to us and our subsidiaries based on tax laws currently in effect and reasonable interpretations of these laws. Because some jurisdictions do not have systems of taxation that are as well established as the system of income taxation used in the U.K. , U.S. or tax regimes used in other major industrialized countries, it may be difficult to anticipate how other jurisdictions will tax our and our subsidiaries’ current and future operations. We and our subsidiaries file consolidated and standalone income tax returns in various jurisdictions. In the normal course of business, our income tax filings are subject to review by various taxing authorities. In connection with such reviews, disputes could arise with the taxing authorities over the interpretation or application of certain income tax rules related to our business in that tax jurisdiction. Such disputes may result in future tax and interest and penalty assessments by these taxing authorities. The ultimate resolution of tax contingencies will take place upon the earlier of (i) the settlement date with the applicable taxing authorities in either cash or agreement of income tax positions or (ii) the date when the tax authorities are statutorily prohibited from adjusting the company’s tax computations. In general, tax returns filed by our company or our subsidiaries for years prior to 2008 are no longer subject to examination by tax authorities. Certain of our subsidiaries are currently involved in income tax examinations in various jurisdictions in which we operate, including Austria (2012 through 2014), Chile (2011 through 2015), the Czech Republic (2013), Germany (2008 through 2014), the Netherlands (2015 through 2016), Panama (2013 through 2015), Poland (2010 and 2013), Trinidad and Tobago (2006 through 2009), the U.S. (2009 through 2011 and 2016) and certain other jurisdictions within the Caribbean and Latin America. Except as noted below, any adjustments that might arise from the foregoing examinations are not expected to have a material impact on our consolidated financial position or results of operations. In the U.S. , we have received notices of adjustment from the Internal Revenue Service with respect to our 2010 and 2009 income tax returns, and have entered into the appeals process with respect to the 2010 and 2009 matters. In Chile, adjustments received from the tax authorities for the tax years 2011 and 2012 are in dispute. We have appealed these adjustments to the Chilean tax court. Also in Chile, we recorded an income tax receivable in connection with the expected utilization of certain net operating loss carryforwards upon the completion of a merger transaction of two indirect subsidiaries of Liberty Global. We are engaged in an ongoing examination by tax authorities in Chile in connection with this receivable and were notified during the third quarter of 2016 that approximately 48% of our claim has been agreed by the tax authorities. We intend to pursue the payment of the remaining portion of this receivable through available method. 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. The changes in our unrecognized tax benefits are summarized below: 2016 2015 2014 in millions Balance at January 1 $ 609.9 $ 513.5 $ 490.9 Reductions for tax positions of prior years (184.2 ) (42.2 ) (50.2 ) Additions for tax positions of prior years 112.9 27.0 64.5 Lapse of statute of limitations (84.6 ) (8.3 ) (1.9 ) Effects of business acquisitions 38.0 — — Additions based on tax positions related to the current year 33.5 142.3 38.2 Foreign currency translation (10.9 ) (22.3 ) (27.0 ) Settlements with tax authorities (13.5 ) (0.1 ) (1.0 ) Balance at December 31 $ 501.1 $ 609.9 $ 513.5 No assurance can be given that any of these tax benefits will be recognized or realized. As of December 31, 2016 , our unrecognized tax benefits included $438.3 million of tax benefits that would have a favorable impact on our effective income tax rate if ultimately recognized, after considering amounts that we would expect to be offset by valuation allowances and other factors. During 2017 , it is reasonably possible that the resolution of ongoing examinations by tax authorities as well as expiration of statutes of limitation could result in reductions to our unrecognized tax benefits related to tax positions taken as of December 31, 2016 . 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 2017 . No assurance can be given as to the nature or impact of any changes in our unrecognized tax positions during 2017 . During 2016 , 2015 and 2014 , the income tax benefit (expense) of our continuing operations includes net income tax benefit (expense) of $15.7 million , ( $10.3 million ) and ( $10.9 million ), respectively, representing the net benefit (accrual) of interest and penalties during the period. Our other long-term liabilities include accrued interest and penalties of $50.1 million at December 31, 2016

Equity [Abstract]
Equity	Equity Capitalization Our authorized share capital consists of an aggregate nominal amount of $20.0 million , consisting of any of the following: (i) Liberty Global Shares (Class A, B or C), each with a nominal value of $0.01 per share, (ii) LiLAC Shares (Class A, B or C), each with a nominal value of $0.01 per share, (iii) preference shares, with a nominal value to be determined by the board of directors, the issuance of one or more classes or series of which as may be authorized by the board of directors, and (iv) any other shares of one or more classes as may be determined by the board of directors or by the shareholders of Liberty Global . Under Liberty Global ’s Articles of Association, effective July 1, 2015, holders of Liberty Global Class A ordinary shares and LiLAC Class A ordinary shares are entitled to one vote for each such share held, and holders of Liberty Global Class B ordinary shares and LiLAC Class B ordinary shares are entitled to 10 votes for each such share held, on all matters submitted to a vote of Liberty Global shareholders at any general meeting (annual or special). Holders of Liberty Global Class C ordinary shares and LiLAC Class C ordinary shares are not entitled to any voting powers except as required by law. At the option of the holder, each Liberty Global Class B ordinary share is convertible into one Liberty Global Class A ordinary share and each LiLAC Class B ordinary share is convertible into one LiLAC Class A ordinary share. One Liberty Global Class A ordinary share is reserved for issuance for each Liberty Global Class B ordinary share that is issued ( 10,805,850 shares issued as of December 31, 2016 ), and one LiLAC Class A ordinary share is reserved for issuance for each LiLAC Class B ordinary share ( 1,888,323 shares issued as of December 31, 2016 ). Additionally, at December 31, 2016 , we have reserved Liberty Global Shares and LiLAC Shares for the issuance of outstanding share-based compensation awards, as set forth in the table below: Liberty Global Shares LiLAC Shares Class A Class B Class C Class A Class B Class C Options 707,293 — 2,754,480 82,818 — 212,602 SARs and PSARs 13,182,578 — 32,139,764 1,973,135 — 4,757,017 PSUs, PGUs, RSUs 3,649,647 333,334 6,652,584 550,359 58,256 1,000,190 Subject to any preferential rights of any outstanding class of our preference shares, the holders of Liberty Global Shares and LiLAC Shares are entitled to dividends as may be declared from time to time by our board of directors from funds available therefore. Such dividends may be declared in favor of Liberty Global Shares and LiLAC Shares , in equal or unequal amounts, or only in favor of the Liberty Global Shares or the LiLAC Shares . There are currently no contractual restrictions on our ability to pay dividends in cash or shares. In the event of our liquidation, dissolution and winding up, after payment or provision for payment of our debts and liabilities and subject to the prior payment in full of any preferential amounts to which our preference shareholders, if any, may be entitled, the holders of Liberty Global Shares and LiLAC Shares will be entitled to receive their proportionate interests, expressed in liquidation units, in any assets available for distribution to our ordinary shares regardless of whether such assets are then attributed to the Liberty Global Group or the LiLAC Group . Pursuant to the terms of our Articles of Association, the liquidation units for each Liberty Global Share and each LiLAC Share are 1 and 0.94893 , respectively. On January 26, 2014, our board of directors approved a share split in the form of a share dividend (the 2014 Share Dividend ), which constituted a bonus issue under our articles of association and English law, of one Liberty Global Class C ordinary share on each outstanding Liberty Global Class A, Class B and Class C ordinary share as of the February 14, 2014 record date. The distribution date for the 2014 Share Dividend was March 3, 2014. All Liberty Global share and per share amounts presented herein give retrospective effect to the 2014 Share Dividend . A summary of the changes in our share capital during 2016 and 2015 is set forth in the table below: Liberty Global Shares LiLAC Shares Old Liberty Global Shares Class A Class B Class C Total Class A Class B Class C Total Class A Class B Class C Total in millions Balance at January 1, 2015 $ — $ — $ — $ — $ — $ — $ — $ — $ 2.5 $ 0.1 $ 6.3 $ 8.9 Repurchase and cancellation of Old Liberty Global Shares — — — — — — — — — — (0.1 ) (0.1 ) Liberty Global call option contracts — — — — — — — — — — (0.1 ) (0.1 ) Balance at June 30, 2015 — — — — — — — — 2.5 0.1 6.1 8.7 Impact of the LiLAC Transaction (note 1) 2.5 0.1 6.1 8.7 0.1 — 0.3 0.4 (2.5 ) (0.1 ) (6.1 ) (8.7 ) Repurchase and cancellation of Liberty Global Shares — — (0.1 ) (0.1 ) — — — — — — — — Liberty Global call option contracts — — (0.1 ) (0.1 ) — — — — — — — — Balance at December 31, 2015 $ 2.5 $ 0.1 $ 5.9 $ 8.5 $ 0.1 $ — $ 0.3 $ 0.4 $ — $ — $ — $ — Impact of the CWC Acquisition (note 4) 0.3 — 0.8 1.1 — — 0.1 0.1 — — — — Repurchase and cancellation of Liberty Global Shares (0.3 ) — (0.4 ) (0.7 ) — — — — — — — — Impact of the LiLAC Distribution (note 4) — — — — 0.4 — 0.8 1.2 — — — — Balance at December 31, 2016 $ 2.5 $ 0.1 $ 6.3 $ 8.9 $ 0.5 $ — $ 1.2 $ 1.7 $ — $ — $ — $ — Share Repurchase Programs As a U.K. incorporated company, we may only elect to repurchase shares or pay dividends to the extent of our “Distributable Reserves.” Distributable Reserves, which are not linked to a U.S. GAAP reported amount, may be created through the earnings of the U.K. parent company and, among other methods, through a reduction in share premium approved by the English Companies Court. Based on the amounts set forth in our 2015 U.K. Companies Act Report dated April 25, 2016, which are our most recent “Relevant Accounts” for the purposes of determining our Distributable Reserves under U.K. law, our Distributable Reserves were $27.9 billion as of December 31, 2015. This amount does not reflect earnings, share repurchases or other activity that occurred in 2016 , each of which impacts the amount of our Distributable Reserves. Our board of directors has approved share repurchase programs for our Liberty Global Shares and, effective November 2016, our LiLAC Shares . Under these plans, we receive authorization to acquire up to the specified amount (before direct acquisition costs) of Class A and Class C Liberty Global Shares or LiLAC Shares , or other authorized securities, from time to time through open market or privately negotiated transactions, which may include derivative transactions. The most recent authorizations provide for the repurchase of up to $4.0 billion and $300.0 million of Liberty Global and LiLAC Class A and/or Class C shares, respectively. The timing of the repurchase of shares or other securities pursuant to our equity repurchase programs, which may be suspended or discontinued at any time, is dependent on a variety of factors, including market conditions. As of December 31, 2016, the remaining amount authorized for repurchases of Liberty Global Shares and LiLAC Shares was $1,943.4 million and $278.6 million , respectively. Subsequent to December 31, 2016 , our board of directors increased the amount authorized under the share repurchase program for our Liberty Global Shares by $1.0 billion . The following table provides details of our share repurchases during 2016 , 2015 and 2014 : Class A ordinary shares Class C ordinary shares Shares repurchased Average price paid per share (a) Shares repurchased Average price paid per share (a) Total cost (a) in millions Liberty Global Shares / Old Liberty Global Shares repurchased during: 2016 32,387,722 $ 32.26 31,557,089 $ 32.43 $ 2,068.0 2015 (b) — $ — 49,984,562 $ 46.91 $ 2,344.5 2014 (c) 8,062,792 $ 42.19 28,401,019 $ 44.25 $ 1,596.9 LiLAC Shares repurchased during 2016 720,800 $ 20.65 313,647 $ 21.19 $ 21.5 _______________ (a) Includes direct acquisition costs and the effects of derivative instruments, where applicable. (b) Amounts relate to repurchases of (i) Old Liberty Global Shares from January 1 through June 30, 2015 and (ii) Liberty Global Shares from July 1 through December 31, 2015. (c) Amounts relate to repurchases of Old Liberty Global Shares . Call Option Contracts From time to time, we enter into call option contracts pursuant to which we contemporaneously (i) sell call options on shares of Liberty Global ordinary shares and (ii) purchase call options on an equivalent number of Liberty Global ordinary shares with an exercise price of zero . These contracts can result in the receipt of cash or Liberty Global ordinary shares. Shares acquired through the exercise of the call options are included in our share repurchases and the net gain on cash settled contracts is recorded as an increase to additional paid-in capital in our consolidated statements of equity. LiLAC Distribution For information regarding the LiLAC Distribution , see note 4 . Acquisition of Interests in VTR and VTR Wireless On March 14, 2014, a subsidiary of VTR Finance acquired each of the noncontrolling ownership interests in VTR and VTR Wireless SpA ( VTR Wireless ) from Inversiones Corp Comm 2 SpA (the VTR NCI Acquisition ), formerly known as Corp Comm S.A. (the VTR NCI Owner ). VTR Wireless was an indirect subsidiary of Liberty Global that was merged with a subsidiary of VTR in December 2014. The consideration for the VTR NCI Acquisition was satisfied by the allotment and issuance of 10,091,178 Old Liberty Global Class C ordinary shares to the VTR NCI Owner . The VTR NCI Acquisition has been accounted for as an equity transaction, the net effect of which was to record the issued Old Liberty Global Class C shares at the $185.4 million carrying value of the acquired noncontrolling interests. Subsidiary Distributions From time to time, Telenet , VTR , CWC and certain other of our subsidiaries make cash distributions to their respective shareholders. Our share of these distributions is eliminated in consolidation and the noncontrolling interest owners’ share of these distributions is reflected as a charge against noncontrolling interests in our consolidated statements of equity. Restricted Net Assets The ability of certain of our subsidiaries to distribute or loan all or a portion of their net assets to our company is limited by the terms of applicable debt facilities.

Share-based Compensation	Share-based Compensation Our share-based compensation expense primarily relates to the share-based incentive awards issued by Liberty Global to its employees and employees of its subsidiaries. A summary of the aggregate share-based compensation expense that is included in our other operating and SG&A expenses is set forth below: Year ended December 31, 2016 2015 2014 in millions Liberty Global: Performance-based incentive awards (a) $ 162.7 $ 157.1 $ 129.9 Other share-based incentive awards 114.9 149.6 99.7 Total Liberty Global (b) 277.6 306.7 229.6 Telenet share-based incentive awards (c) 12.2 9.2 14.6 Other 7.1 2.3 13.0 Total $ 296.9 $ 318.2 $ 257.2 Included in: Other operating expense: Liberty Global Group $ 3.3 $ 3.1 $ 4.8 LiLAC Group 1.4 0.3 2.8 Total other operating expense 4.7 3.4 7.6 SG&A expense: Liberty Global Group 278.2 312.7 240.8 LiLAC Group 14.0 2.1 8.8 Total SG&A expense 292.2 314.8 249.6 Total $ 296.9 $ 318.2 $ 257.2 _______________ (a) Includes share-based compensation expense related to (i) Liberty Global PSU s, including amounts resulting from the 2016 PSU s, as described and defined below, (ii) a challenge performance award plan for certain executive officers and key employees (the Challenge Performance Awards ) and (iii) PGUs to our Chief Executive Officer, as described below. The Challenge Performance Awards include PSAR s and PSU s. (b) In connection with the LiLAC Transaction , our compensation committee approved modifications to our outstanding share-based incentive awards (the 2015 Award Modifications ) in accordance with the underlying share-based incentive plans. The objective of our 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 our 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 share-based compensation expense should be recorded as a result of the 2015 Award Modifications , we were 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 2015 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, SAR s 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 2015 Award Modifications had been used. Accordingly, the Black-Scholes fair values of our options, SAR s and PSAR s increased as a result of the 2015 Award Modifications , resulting in incremental share-based compensation of $99.3 million , including $16.1 million and $69.3 million recognized during 2016 and 2015, respectively, and $13.9 million that will be recognized in future periods through 2019 as the related awards vest. (c) Represents the share-based compensation expense associated with Telenet ’s share-based incentive awards, which, at December 31, 2016 , included (i) warrants and employee stock options ( 2,473,404 awards outstanding at a weighted average exercise price of €43.70 ( $46.09 )), (ii) performance-based specific stock option plans for the Chief Executive Officer ( 745,000 awards outstanding at a weighted average exercise price of €40.60 ( $42.82 )), (iii) performance-based share awards ( 173,640 awards outstanding) and (iv) performance-based specific stock option plans for employees ( 18,750 awards outstanding at a weighted average exercise price of €48.83 ( $51.50 )). As of December 31, 2016 , $450.4 million of total unrecognized compensation cost related to our Liberty Global share-based compensation awards is expected to be recognized as an expense by our company in the future over a weighted-average period of approximately 2.5 years . The following table summarizes certain information related to the share-based incentive awards granted and exercised with respect to Liberty Global ordinary shares: Year ended December 31, 2016 2015 2014 Assumptions used to estimate fair value of options, SARs and PSARs granted: Risk-free interest rate 0.88 - 1.49% 0.96 - 1.89% 0.81 - 1.77% Expected life 3.2 - 5.5 years 3.0 - 5.5 years 3.1 - 5.1 years Expected volatility 27.4 - 42.9% 23.1 - 30.1% 25.1 - 28.7% Expected dividend yield none none none Weighted average grant-date fair value per share of awards granted: Options $ 10.40 $ 14.73 $ 11.40 SARs $ 8.60 $ 10.76 $ 8.93 PSARs $ — $ — $ 8.15 RSUs $ 36.67 $ 51.85 $ 40.68 PSUs $ 33.97 $ 51.57 $ 40.42 PGUs $ — $ — $ 44.04 Total intrinsic value of awards exercised (in millions): Options $ 16.9 $ 106.8 $ 126.6 SARs $ 42.2 $ 51.7 $ 48.7 PSARs $ 0.7 $ 0.2 $ 0.4 Cash received from exercise of options (in millions) $ 17.4 $ 40.5 $ 54.8 Income tax benefit related to share-based compensation (in millions) $ 55.2 $ 67.4 $ 54.6 Share Incentive Plans — Liberty Global Ordinary Shares Incentive Plans As of December 31, 2016 , we are authorized to grant incentive awards under the Liberty Global 2014 Incentive Plan and the Liberty Global 2014 Nonemployee Director Incentive Plan. Generally, we may grant non-qualified share options, SAR s, restricted shares, RSU s, cash awards, performance awards or any combination of the foregoing under either of these incentive plans (collectively, awards). Ordinary shares issuable pursuant to awards made under these incentive plans will be made available from either authorized but unissued shares or shares that have been issued but reacquired by our company. Awards may be granted at or above fair value in any class of ordinary shares. The maximum number of Liberty Global ordinary shares with respect to which awards may be issued under the Liberty Global 2014 Incentive Plan and the Liberty Global 2014 Nonemployee Director Incentive Plan is 105 million (of which no more than 50.25 million shares may consist of Class B ordinary shares) and 10.5 million , respectively, in each case, subject to anti-dilution and other adjustment provisions in the respective plan. As of December 31, 2016 , the Liberty Global 2014 Incentive Plan and the Liberty Global 2014 Nonemployee Director Incentive Plan had 64,795,919 and 9,789,929 ordinary shares available for grant, respectively. Awards (other than performance-based awards) under the Liberty Global 2014 Incentive Plan generally (i) vest 12.5% on the six month anniversary of the grant date and then vest at a rate of 6.25% each quarter thereafter and (ii) expire seven years after the grant date. Awards (other than RSU s) issued under the Liberty Global 2014 Nonemployee Director Incentive Plan generally vest in three equal annual installments, provided the director continues to serve as director immediately prior to the vesting date, and expire seven years after the grant date. RSU s vest on the date of the first annual general meeting of shareholders following the grant date. These awards may be granted at or above fair value in any class of ordinary shares. Awards under the VM Incentive Plan issued prior to the June 7, 2013 acquisition of Virgin Media have a 10 -year term and become fully exercisable within five years of continued employment. Awards (other than performance-based awards) issued under the Liberty Global 2005 Incentive Plan and issued under the VM Incentive Plan after June 7, 2013 generally (i) vest 12.5% on the six month anniversary of the grant date and then vest at a rate of 6.25% each quarter thereafter and (ii) expire seven years after the grant date. All awards issued under the Liberty Global 2005 Director Incentive Plan were fully vested as of December 31, 2016, and other than RSUs, expire 7 to 10 years after the grant date. RSU s vest on the date of the first annual general meeting of shareholders following the grant date. No further awards will be granted under the Liberty Global 2005 Incentive Plan , the Liberty Global 2005 Director Incentive Plan or the VM Incentive Plan . Performance Awards The following is a summary of the material terms and conditions with respect to our performance-based awards for certain executive officers and key employees. Liberty Global PSU s Equity awards are granted to executive officers and key employees based on a target annual equity value for each executive and key employee, of which approximately two-thirds would be delivered in the form of PSU s and approximately one-third in the form of an annual award of SAR s. Each currently-outstanding PSU represents the right to receive one Liberty Global or LiLAC Class A or Class C ordinary share, as applicable, subject to performance and vesting. Although PSU s are generally granted on an annual basis, no PSU s will be granted in 2017 to recipients of the 2016 PSUs , as defined and described below. In March 2015, our compensation committee approved the grant of PSU s to executive officers and key employees (the 2015 PSU s ). The performance plan for the 2015 PSU s covered a two-year period ending December 31, 2016 and included a performance target based on the achievement of a specified compound annual growth rate ( CAGR ) in a consolidated Adjusted OIBDA metric (as defined in note 18 ). The performance target was adjusted for events such as acquisitions, dispositions and changes in foreign currency exchange rates that affect comparability ( Adjusted OIBDA CAGR ), and the participant’s annual performance ratings during the two -year performance period. A performance range of 75% to 125% of the target Adjusted OIBDA CAGR will result in award recipients earning 50% to 150% of their respective PSU s, subject to reduction or forfeiture based on individual performance. The percentage of the 2015 PSU s that has been earned by participants has not been finalized. The 2015 PSU s will vest 50% on each of April 1 and October 1 of 2017. In February 2016, our compensation committee approved the grant of PSU s to executive officers and key employees (the 2016 PSUs ) pursuant to a performance plan that is based on the achievement of a specified Adjusted OIBDA CAGR during the three -year period ended December 31, 2018. The 2016 PSUs require delivery of a compound annual growth rate of our consolidated Adjusted OIBDA CAGR of 6.0% during the three -year performance period, with over- and under-performance payout opportunities should the Adjusted OIBDA CAGR exceed or fail to meet the target, as applicable. The performance payout may be adjusted at the compensation committee’s discretion for events that may affect comparability, such as changes in foreign currency exchange rates and accounting principles or policies. A performance range of 75% to 167.5% of the target Adjusted OIBDA CAGR will generally result in award recipients earning 75% to 300% of their target 2016 PSUs , subject to reduction or forfeiture based on individual performance. The earned 2016 PSUs will vest 50% on each of April 1, 2019 and October 1, 2019. Liberty Global Performance Grant Award Effective April 30, 2014, our compensation committee authorized the grant of PGUs to our Chief Executive Officer, comprising a total of one million PGUs with respect to Class A Old Liberty Global Shares and one million PGUs with respect to Class B Old Liberty Global Shares . The PGUs , which were subject to a performance condition that was achieved in 2014, vest in three equal annual installments, the first of which occurred on March 15, 2015. Our Chief Executive Officer also received 41,589 PGUs with respect to each Class A and Class B LiLAC Shares as a result of the LiLAC Distribution in 2016 and 33,333 PGUs with respect to each Class A and Class B LiLAC Shares as a result of the LiLAC Transaction in 2015. Each of these additional distributions vest over the same period as the May 1, 2014 award grant described above. Liberty Global Challenge Performance Awards Effective June 24, 2013, our compensation committee approved the Challenge Performance Awards , which consisted solely of PSAR s for our senior executive officers and a combination of PSAR s and PSU s for our other executive officers and key employees. Each PSU represented the right to receive one Liberty Global or LiLAC Class A or Class C ordinary share, as applicable. The performance criteria for the Challenge Performance Awards was based on the participant’s performance and achievement of individual goals in each of the years 2013, 2014 and 2015. As a result of satisfying performance conditions, 100% of the then outstanding Challenge Performance Awards vested and became fully exercisable on June 24, 2016. The PSAR s have a term of seven years and base prices equal to the respective market closing prices of the applicable class on the grant date. LiLAC Distribution In connection with the LiLAC Distribution , our compensation committee approved modifications to our outstanding share-based incentive awards (the 2016 Award Modification ) in accordance with the underlying share-based incentive plans. The objective of our compensation committee was to ensure a relatively unchanged intrinsic value of outstanding equity awards before and after the LiLAC Distribution . The mechanism to modify outstanding share-based incentive awards, as approved by our compensation committee, utilized an analysis of the prices of the respective shares before and after the share issuance. Based upon this approach, we determined the incremental value associated with the 2016 Award Modification was immaterial. As a result, we did not recognize any incremental share-based compensation expense associated with the 2016 Award Modification . The impact of the LiLAC Distribution is separately presented in the below tables.

Compensation and Retirement Disclosure [Abstract]
Defined Benefit Plans	Defined Benefit Plans Certain of our subsidiaries maintain various funded and unfunded defined benefit plans for their employees. A significant portion of these defined benefit plans are closed to new entrants and existing participants do not accrue any additional benefits. The table below provides summary information on our defined benefit plans: Year ended December 31, 2016 2015 2014 in millions Projected benefit obligation $ 3,200.3 $ 1,188.3 $ 1,247.6 Fair value of plan assets (a) $ 3,108.7 $ 1,092.6 $ 1,122.7 Net liability $ 91.6 $ 95.7 $ 124.9 Net periodic pension cost (b) $ 10.1 $ 11.8 $ 9.6 _______________ (a) The fair value of plan assets at December 31, 2016 includes $1,707.4 million , $199.1 million and $1,202.2 million of assets that are valued based on Level 1, Level 2 and Level 3 inputs, respectively, of the fair value hierarchy (as further described in note 8 ). Our plan assets comprise investments in debt securities, equity securities, hedge funds, insurance contracts and certain other assets (including $1,018.3 million of investments valued using Level 3 inputs that are held by the CWSF , as defined and described below). (b) The 2016 and 2015 amounts exclude aggregate curtailment gains of $1.4 million and $7.9 million , respectively, which are included in impairment, restructuring and other operating items, net, in our consolidated statements of operations. At December 31, 2016 , the Cable & Wireless Superannuation Fund (the CWSF ), which is CWC ’s largest defined benefit plan, had (i) a projected benefit obligation of $1,675.7 million , (ii) fair value of plan assets of $1,666.0 million and (iii) a funded status deficit of $9.7 million . During the period from April 1, 2016 through December 31, 2016, CWC made cash contributions to the CWSF of $44.3 million (including $1.1 million of contributions made subsequent to the completion of the CWC Acquisition), which was based in part on the triennial actuarial funding valuation as of March 31, 2013. CWC ’s acquisition of Columbus constituted a “change of control” under the contingent funding agreement (the Contingent Funding Agreement ) between CWC and the trustee of the CWSF and, therefore, the trustee of the CWSF has the right to drawdown on the $123.5 million letters of credit that were put in place in connection with the acquisition of Columbus pursuant to the terms of the Contingent Funding Agreement . Based on the pending outcome of the triennial actuarial valuation as of March 31, 2016, which is expected to be completed during the second quarter of 2017, CWC ’s contributions necessary to fund the CWSF by April 2019 are currently expected to range from nil to $28.4 million per year during 2017, 2018 and 2019. CWC is currently in negotiations with the trustee of the CWSF with respect to the future funding requirements of the CWSF and the outstanding letters of credit with a view to addressing the remaining deficit through future contributions over a period of time similar in structure to prior triennial period contribution schedules. No assurance can be given as to the outcome of such negotiations. Based on December 31, 2016 exchange rates and information available as of that date, our subsidiaries’ contributions to their respective defined benefit plans in 2017 are expected to aggregate $88.2 million , including $29.6 million attributable to the CWSF

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments In the normal course of business, we have entered into agreements that commit our company to make cash payments in future periods with respect to network and connectivity commitments, programming contracts, purchases of customer premises and other equipment and services, non-cancellable operating leases and other items. The following table sets forth the U.S. dollar equivalents of such commitments as of December 31, 2016 : Payments due during: 2017 2018 2019 2020 2021 Thereafter Total in millions Network and connectivity commitments $ 738.8 $ 386.9 $ 308.9 $ 257.4 $ 240.6 $ 868.2 $ 2,800.8 Programming commitments 1,041.2 900.5 457.2 183.5 62.1 93.1 2,737.6 Purchase commitments 1,236.9 212.6 145.9 102.6 21.0 70.3 1,789.3 Operating leases 133.5 113.2 94.0 73.8 60.7 249.0 724.2 Other commitments 46.7 15.0 12.2 8.5 7.4 14.4 104.2 Total (a) $ 3,197.1 $ 1,628.2 $ 1,018.2 $ 625.8 $ 391.8 $ 1,295.0 $ 8,156.1 _______________ (a) The commitments included in this table do not reflect any liabilities that are included in our December 31, 2016 consolidated balance sheet. Network and connectivity commitments include (i) Telenet ’s commitments for certain operating costs associated with its leased network, (ii) commitments associated with our MVNO agreements and (iii) service commitments associated with our network extension projects, primarily in the U.K. Telenet ’s commitments for certain operating costs are subject to adjustment based on changes in the network operating costs incurred by Telenet with respect to its own networks. These potential adjustments are not subject to reasonable estimation and, therefore, are not included in the above table. The amounts reflected in the above table with respect to certain of our MVNO commitments represent fixed minimum amounts payable under these agreements and, therefore, may be significantly less than the actual amounts we ultimately pay in these periods. Programming commitments consist of obligations associated with certain of our programming, studio output and sports rights contracts that are enforceable and legally binding on us as we have agreed to pay minimum fees without regard to (i) the actual number of subscribers to the programming services, (ii) whether we terminate service to a portion of our subscribers or dispose of a portion of our distribution systems or (iii) whether we discontinue our premium sports services. In addition, programming commitments do not include increases in future periods associated with contractual inflation or other price adjustments that are not fixed. Accordingly, the amounts reflected in the above table with respect to these contracts are significantly less than the amounts we expect to pay in these periods under these contracts. Historically, payments to programming vendors have represented a significant portion of our operating costs, and we expect that this will continue to be the case in future periods. In this regard, our total programming and copyright costs aggregated $2,449.4 million (including $2,104.5 million for the Liberty Global Group and $344.9 million for the LiLAC Group ), $2,313.9 million (including $2,066.6 million for the Liberty Global Group and $247.3 million for the LiLAC Group ) and $2,160.0 million (including $1,928.0 million for the Liberty Global Group and $232.0 million for the LiLAC Group ) during 2016 , 2015 and 2014 , respectively. Purchase commitments include unconditional and legally binding obligations related to (i) the purchase of customer premises and other equipment and (ii) certain service-related commitments, including call center, information technology and maintenance services. Commitments arising from acquisition agreements are not reflected in the above table. For information regarding our commitments under acquisition agreements, see note 4 . 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 2016 , 2015 and 2014 , see note 7 . For information regarding our defined benefit plans, see note 15 . 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. Rental expense under non-cancellable operating lease arrangements amounted to $250.6 million (including $205.2 million for the Liberty Global Group and $45.4 million for the LiLAC Group ), $219.0 million (including $204.7 million for the Liberty Global Group and $14.3 million for the LiLAC Group ) and $268.3 million (including $252.0 million for the Liberty Global Group and $16.3 million for the LiLAC Group ) during 2016 , 2015 and 2014 , respectively. It is expected that in the normal course of business, operating leases that expire generally will be renewed or replaced by similar leases. We have established various defined contribution benefit plans for our and our subsidiaries’ employees. Our aggregate expense for matching contributions under the various defined contribution employee benefit plans was $76.8 million (including $70.4 million for the Liberty Global Group and $6.4 million for the LiLAC Group ), $76.7 million (including $75.0 million for the Liberty Global Group and $1.7 million for the LiLAC Group ) and $63.2 million (including $61.7 million for the Liberty Global Group and $1.5 million for the LiLAC Group ) during 2016 , 2015 and 2014 , respectively. 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 the PICs announced a non-binding agreement-in-principle to transfer the analog and digital television activities of the PICs , including all existing subscribers to Telenet . Subsequently, Telenet and the PICs entered into a binding agreement (the 2008 PICs Agreement ), which closed effective October 1, 2008 . Beginning in December 2007 , Proximus NV/SA ( Proximus ), the incumbent telecommunications operator in Belgium, instituted several proceedings seeking to block implementation of these agreements. Proximus lodged summary proceedings with the President of the Court of First Instance of Antwerp to obtain a provisional injunction preventing the PICs from effecting the agreement-in-principle and initiated a civil procedure on the merits claiming the annulment of the agreement-in-principle. In March 2008 , the President of the Court of First Instance of Antwerp ruled in favor of Proximus in the summary proceedings, which ruling was overturned by the Court of Appeal of Antwerp in June 2008 . Proximus brought this appeal judgment before the Cour de Cassation (the Belgian Supreme Court ), which confirmed the appeal judgment in September 2010. On April 6, 2009 , the Court of First Instance of Antwerp ruled in favor of the PICs and Telenet in the civil procedure on the merits, dismissing Proximus ’s request for the rescission of the agreement-in-principle and the 2008 PICs Agreement . On June 12, 2009 , Proximus appealed this judgment with the Court of Appeal of Antwerp. In this appeal, Proximus is now also seeking compensation for damages should the 2008 PICs Agreement not be rescinded. While these proceedings were suspended indefinitely, other proceedings were initiated, which resulted in a ruling by the Belgian Council of State in May 2014 annulling (i) the decision of the PICs not to organize a public market consultation and (ii) the decision from the PICs ’ board of directors to approve the 2008 PICs Agreement . In December 2015, Proximus resumed the civil proceedings pending with the Court of Appeal of Antwerp seeking to have the 2008 PICs Agreement annulled and claiming damages of €1.4 billion ( $1.5 billion ). Telenet intends to defend itself vigorously in the resumed proceedings and does not expect an outcome before the end of 2017. No assurance can be given as to the outcome of these or other proceedings. However, an unfavorable outcome of existing or future proceedings could potentially lead to the annulment of the 2008 PICs Agreement and/or to an obligation of Telenet to pay compensation for damages, subject to the relevant provisions of the 2008 PICs Agreement , which stipulate that Telenet is responsible for damages in excess of €20.0 million ( $21.1 million ). We do not expect the ultimate resolution of this matter to have a material impact on our results of operations, cash flows or financial position. No amounts have been accrued by us with respect to this matter as the likelihood of loss is not considered to be probable. Deutsche Telekom Litigation. On December 28, 2012, Unitymedia filed a lawsuit against Deutsche Telekom 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 ( $80 million ) for 2012) by approximately two-thirds and the return of similarly calculated overpayments from 2009 through the ultimate settlement date, plus accrued interest. In October 2016, the first instance court dismissed this action. We have appealed this decision, however, the resolution of this matter may take several years and no assurance can be given that Unitymedia ’s claims will be successful. Any recovery by Unitymedia will not be reflected in our consolidated financial statements until such time as the final disposition of this matter has been reached. 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 ( PRTC ) 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 PRTC 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). In July 2016, the judge presiding over the PRTC Claim in the United States District Court for the District of Maine (the District Court ) granted OneLink summary judgment that dismissed the PRTC Claim in its entirety. PRTC filed an appeal of the District Court’s decision with the United States First Circuit Court of Appeals. Based on our assessment of the PRTC Claim on appeal and the Class Action Claim , we have determined that the possibility of loss is remote. As a result, we will not report on this matter in future filings. In connection with the July 2016 decision, we have released our previously-recorded provision and related indemnification asset associated with the PRTC Claim , resulting in a $5.1 million reduction to our SG&A expenses during the third quarter of 2016. In December 2016, we received $7.5 million related to the reimbursement of legal fees we incurred in connection with the PRTC Claim , resulting in a reduction to our SG&A expenses during the fourth quarter of 2016 and the release of the former owners of OneLink from their obligations under the indemnification agreement entered into in connection with the OneLink Acquisition . Belgium Regulatory Developments. In December 2010, the Belgisch Instituut voor Post en Telecommunicatie and the regional regulators for the media sectors (together, the Belgium Regulatory Authorities ) published their respective draft decisions reflecting the results of their joint analysis of the broadcasting market in Belgium. The Belgium Regulatory Authorities adopted a final decision on July 1, 2011 (the July 2011 Decision ) with some minor revisions. The regulatory obligations imposed by the July 2011 Decision include (i) an obligation to make a resale offer at “retail minus’’ of the cable analog package available to third party operators (including Proximus ), (ii) an obligation to grant third-party operators (except Proximus ) access to digital television platforms (including the basic digital video package) at “retail minus,” and (iii) an obligation to make a resale offer at “retail minus’’ of broadband internet access available to beneficiaries of the digital television access obligation that wish to offer bundles of digital video and broadband internet services to their customers (except Proximus ). In February 2012, Telenet submitted draft reference offers regarding the obligations described above, and the Belgium Regulatory Authorities published the final decision on September 9, 2013. Telenet has implemented the access obligations as described in its reference offers and, on March 1, 2016, Orange Belgium NV ( Orange Belgium ), formerly known as Mobistar SA, launched a commercial offer combining a cable TV package and broadband internet access for certain of their mobile customers. In addition, as a result of the November 2014 decision by the Brussels Court of Appeal described below, on November 14, 2014, Proximus submitted a request to Telenet to commence access negotiations. Telenet contests this request and has asked the Belgium Regulatory Authorities to assess the reasonableness of the Proximus request. The timing for a decision regarding this assessment by the Belgium Regulatory Authorities is not known. On December 14, 2015, the Belgium Regulatory Authorities published a draft decision, which amended previously-issued decisions and sets forth the “retail minus” tariffs of minus 26% for basic television (basic analog and digital video package) and minus 18% for the bundle of basic television and broadband internet services during an initial two -year period. Following this two -year period, the tariffs would change to minus 15% and 7% , respectively. The draft decision was notified to the European Commission and a final decision was adopted on February 19, 2016. A “retail minus” method of pricing involves a wholesale tariff calculated as the retail price for the offered service by Telenet , excluding VAT and copyrights, and further deducting the retail costs avoided by offering the wholesale service (such as costs for billing, franchise, consumer service, marketing and sales). Telenet filed an appeal against the July 2011 Decision with the Brussels Court of Appeal. On November 12, 2014, the Brussels Court of Appeal rejected Telenet ’s appeal of the July 2011 Decision and accepted Proximus ’s claim that Proximus should be allowed access to Telenet ’s, among other operators, digital television platform and the resale of bundles of digital video and broadband internet services. On November 30, 2015, Telenet filed an appeal of this decision with the Belgian Supreme Court . In 2014, Telenet and wireless operator Orange Belgium each filed an appeal with the Brussels Court of Appeal against the initial retail minus decisions. These appeals are still pending. On April 25, 2016, Telenet also filed an appeal with the Brussels Court of Appeal challenging the February 19, 2016 retail minus decision. There can be no certainty that Telenet ’s appeals will be successful. 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. Financial Transactions Tax. Certain countries in the European Union ( E.U. ), including Germany, Austria and Slovakia, are participating in an enhanced cooperation procedure to introduce a financial transactions tax (the FTT ). Under the draft language of the FTT proposal, a wide range of financial transactions could be taxed at rates of at least 0.01% for derivative transactions based on the notional amount and 0.1% for other covered financial transactions based on the underlying transaction price. Each of the individual countries would be permitted to determine an exact rate, which could be higher than the proposed rates of 0.01% and 0.1% . Any implementation of the FTT could have a global impact because it would apply to all financial transactions where a financial institution is involved (including unregulated entities that engage in certain types of covered activity) and either of the parties (whether the financial institution or its counterparty) is in one of the participating countries. Although there continues to be ongoing discussions in the relevant countries around the FTT , uncertainty remains as to if and when the FTT will be implemented and the breadth of its application. Based on our understanding of the current status of the potential FTT , we do not expect that any implementation of the FTT would occur before 2018. Any imposition of the FTT could increase banking fees and introduce taxes on internal transactions that we currently perform. Due to the uncertainty regarding the FTT , we are currently unable to estimate the financial impact that the FTT could have on our results of operations, cash flows or financial position. Virgin Media VAT Matters. Virgin Media ’s application of VAT with respect to certain revenue generating activities has been challenged by the U.K. tax authorities. Virgin Media has estimated its maximum exposure in the event of an unfavorable outcome to be £46.6 million ( $57.5 million ) as of December 31, 2016 . No portion of this exposure has been accrued by Virgin Media as the likelihood of loss is not considered to be probable. A court hearing was held at the end of September 2014 in relation to the U.K. tax authorities’ challenge and the timing of the court’s decision is uncertain . On March 19, 2014, the U.K. government announced a change in legislation with respect to the charging of VAT in connection with prompt payment discounts such as those that we offer to our fixed-line telephony customers. This change, which took effect on May 1, 2014, impacted our company and some of our competitors. The U.K. tax authority issued a decision in the fourth quarter of 2015 challenging our application of the prompt payment discount rules prior to the May 1, 2014 change in legislation. We have appealed this decision. As part of the appeal process, we were required to make aggregate payments of £67.0 million ( $99.1 million at the respective transaction dates), which included the challenged amount of £63.7 million and related interest of £3.3 million . The aggregate amount paid does not include penalties, which could be significant in the unlikely event that penalties were to be assessed. This matter will likely be subject to court proceedings that could delay the ultimate resolution for an extended period of time. No portion of this potential exposure has been accrued by our company as the likelihood of loss is not considered to be probable. Hungary VAT Matter. In February 2016, our DTH operations in Luxembourg received a second instance decision from the Hungarian tax authorities as a result of an audit with respect to VAT payments that the Hungarian tax authorities conducted for the years 2010 through 2012. The Hungarian tax authorities assessed our DTH operations with an obligation to pay VAT for the years audited of HUF 5,413.2 million ( $18.5 million ), excluding interest and penalties, which could be significant. We believe that our DTH operations have operated in compliance with all applicable rules, regulations and interpretations thereof, including a binding tax ruling that we received from the Hungarian government in 2010. In October 2016, a Budapest court disagreed with the tax authorities and dismissed the assessment. On February 2, 2017, the Hungarian tax authorities appealed the Budapest court decision to the Hungarian Supreme Court. No portion of this exposure has been accrued by us as the likelihood of loss is not considered to be probable. Other Regulatory Issues. Video distribution, broadband internet, fixed-line telephony, mobile and content businesses are regulated in each of the countries in which we operate. The scope of regulation varies from country to country, although in some significant respects regulation in European markets is harmonized under the regulatory structure of the E.U. Adverse regulatory developments could subject our businesses to a number of risks. Regulation, including conditions imposed on us by competition or other authorities as a requirement to close acquisitions or dispositions, could limit growth, revenue and the number and types of services offered and could lead to increased operating costs and property and equipment additions. In addition, regulation may restrict our operations and subject them to further competitive pressure, including pricing restrictions, interconnect and other access obligations, and restrictions or controls on content, including content provided by third parties. Failure to comply with current or future regulation could expose our businesses to various penalties. We have been notified of a fourfold increase in the rateable value of our network and other assets in the U.K. that is scheduled to become effective on April 1, 2017. This increase will affect the amount we pay for network infrastructure charges as the annual amount payable to the U.K. government is calculated by applying a percentage multiplier to the rateable value of assets. This proposed change, together with a similar proposed change in Ireland, would result in significant increases in our network infrastructure charges. We estimate that the aggregate amount of these increases will be approximately £30 million ( $37 million ) during 2017 and will build to a maximum aggregate increase of up to £120 million ( $148 million ) in 2021. We believe that the proposed increases are excessive, and we will challenge the underlying methodology and assumptions. In addition to the foregoing items, we have contingent liabilities related to matters arising in the ordinary course of business including (i) legal proceedings, (ii) issues involving VAT

Segment Reporting, Measurement Disclosures [Abstract]
Segment Reporting	Segment Reporting We generally identify our reportable segments as 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 because it represents a transparent view of our recurring operating performance that is unaffected by our capital structure and allows management to (1) readily view operating trends, (2) perform analytical comparisons and benchmarking between segments and (3) identify strategies to improve operating performance in the different countries in which we operate. A reconciliation of total segment Adjusted OIBDA to our earnings (loss) from continuing operations before income taxes is presented below. As of December 31, 2016 , our reportable segments are as follows: • European Division : • U.K./Ireland • Belgium • The Netherlands (through the completion of the Dutch JV Transaction ) • Germany • Switzerland/Austria • Central and Eastern Europe • LiLAC Division: • CWC • Chile • Puerto Rico On December 31, 2016 , we completed the Dutch JV Transaction , whereby we contributed Ziggo Group Holding (including Ziggo Sport ) to the Dutch JV . Accordingly, our results of operations include the operations of Ziggo Group Holding and Ziggo Sport for all periods presented while our December 31, 2016 consolidated balance sheet excludes such entities. In our segment presentation, Ziggo Group Holding (exclusive of Ziggo Sport, which became a subsidiary of Ziggo Group Holding in October 2016) is separately reported as “ The Netherlands ” and Ziggo Sport is included in our “ Corporate and Other ” category. Beginning with the first quarter of 2017, we expect to present the Dutch JV as a reportable segment. For additional information regarding the Dutch JV Transaction , see note 5 to our consolidated financial statements. All of the reportable segments set forth above derive their revenue primarily from residential and B2B services, including video, broadband internet and fixed-line telephony services and, with the exception of Puerto Rico, mobile services. At December 31, 2016 , our operations in the European Division provided residential and B2B services in 11 European countries and DTH services to customers in the Czech Republic, Hungary, Romania and Slovakia through a Luxembourg-based organization that we refer to as “ UPC DTH .” In addition to UPC DTH , our Central and Eastern Europe segment includes our broadband communications operations in the Czech Republic, Hungary, Poland, Romania and Slovakia. The European Division ’s central and other category includes (i) costs associated with certain centralized functions, including billing systems, network operations, technology, marketing, facilities, finance and other administrative functions, and (ii) intersegment eliminations within the European Division . In addition, our LiLAC Division provides residential and B2B services in (a) 18 countries, all but one of which are located in Latin America and the Caribbean, through CWC , (b) Chile through VTR and (c) Puerto Rico through Liberty Puerto Rico . CWC also provides (1) B2B services in certain other countries in Latin America and the Caribbean and (2) wholesale services over its sub-sea and terrestrial networks that connect over 30 markets in that region. The corporate and other category for the Liberty Global Group includes less significant consolidated operating segments that provide programming and other services, including Ziggo Sport through December 31, 2016 . Intersegment eliminations primarily represent the elimination of intercompany transactions between our broadband communications and programming operations. Inter-group eliminations 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 , Liberty Puerto Rico and certain subsidiaries of CWC that are not wholly owned, we consolidate 100% of the revenue and expenses of these entities in our consolidated statements of operations despite the fact that third parties own significant interests in these entities. The noncontrolling owners’ interests in the operating results of Telenet , Liberty Puerto Rico , certain subsidiaries of CWC and other less significant majority-owned subsidiaries are reflected in net earnings or loss attributable to noncontrolling interests in our consolidated statements of operations.

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 $313.4 million , $212.7 million and $245.0 million during 2016 , 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 or home office ( SOHO ) subscribers. SOHO subscribers pay a premium price to receive expanded service levels along with video, broadband internet, fixed-line telephony or mobile services that are the same or similar to the mass marketed products offered to our residential subscribers. Revenue from SOHO subscribers, which is included in subscription revenue, aggregated $491.8 million , $319.2 million and $216.5 million during 2016 , 2015 and 2014 , respectively. (d) Other revenue includes, among other items, interconnect fees, mobile handset sales, channel carriage fees and installation fees .

Summary of Significant Accoun30

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Estimates	Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. ( U.S. GAAP ) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used in accounting for, among other things, the valuation of acquisition-related assets and liabilities, allowances for uncollectible accounts, programming and copyright expenses, 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.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation, including the reclassification of deferred financing costs from other long-term assets to long-term debt and capital lease obligations and the reclassification of certain costs between programming and other direct costs of services, other operating and SG&A expenses. For additional information regarding the change in the classification of deferred financing costs, see “Accounting Changes” in note 2 .
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include our accounts and the accounts of all voting interest entities where we exercise a controlling financial interest through the ownership of a direct or indirect controlling voting interest and variable interest entities for which our company is the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Cash equivalents consist of money market funds and other investments that are readily convertible into cash and have maturities of three months or less at the time of acquisition. We record money market funds at the net asset value reported by the investment manager as there are no restrictions on our ability, contractual or otherwise, to redeem our investments at the stated net asset value reported by the investment manager. Restricted cash consists of cash held in restricted accounts, including cash held as collateral for debt and other compensating balances. Restricted cash amounts that are required to be used to purchase long-term assets or repay long-term debt are classified as long-term assets. All other cash that is restricted to a specific use is classified as current or long-term based on the expected timing of the disbursement. At December 31, 2016 and 2015 , our current and long-term restricted cash balances aggregated $39.1 million and $127.9 million , respectively. Our significant non-cash investing and financing activities are disclosed in our consolidated statements of equity and in notes 4 , 7 , 9 , and 10
Trade Receivables	Trade Receivables Our trade receivables are reported net of an allowance for doubtful accounts. Such allowance aggregated $193.4 million and $115.7 million at December 31, 2016 and 2015 , respectively. The allowance for doubtful accounts is based upon our assessment of probable loss related to uncollectible accounts receivable. We use a number of factors in determining the allowance, including, among other things, collection trends, prevailing and anticipated economic conditions and specific customer credit risk. The allowance is maintained until either payment is received or the likelihood of collection is considered to be remote.
Investments	Investments We make elections, on an investment-by-investment basis, as to whether we measure our investments at fair value. Such elections are generally irrevocable. With the exception of those investments over which we exercise significant influence, we generally elect the fair value method. For those investments over which we exercise significant influence, we generally elect the equity method. Under the fair value method, investments are recorded at fair value and any changes in fair value are reported in realized and unrealized gains or losses due to changes in fair values of certain investments and debt, net, in our consolidated statements of operations. All costs directly associated with the acquisition of an investment to be accounted for using the fair value method are expensed as incurred. Under the equity method of accounting, investments are recorded at cost and are subsequently increased or reduced to reflect our share of income or losses of the investee. All costs directly associated with the acquisition of an investment to be accounted for using the equity method are included in the carrying amount of the investment. For additional information regarding our fair value and equity method investments, see notes 6 and 8 . Under the equity method, investments, originally recorded at cost, are adjusted to recognize our share of net earnings or losses of the affiliates as they occur rather than as dividends or other distributions are received, with our recognition of losses generally limited to the extent of our investment in, and advances and commitments to, the investee. The portion of the difference between our investment and our share of the net assets of the investee that represents goodwill is not amortized, but continues to be considered for impairment. Intercompany profits on transactions with equity affiliates for which assets remain on our or our investee’s balance sheet are eliminated to the extent of our ownership in the investee. Dividends from publicly-traded investees that are not accounted for under the equity method are recognized when declared as dividend income in our consolidated statements of operations. Dividends from our equity method investees and all of our privately-held investees are reflected as reductions of the carrying values of the applicable investments. Dividends that are deemed to be (i) returns on our investments are included in cash flows from operating activities in our consolidated statements of cash flows and (ii) returns of our investments are included in cash flows from investing activities in our consolidated statements of cash flows. We continually review all of our equity and cost method investments to determine whether a decline in fair value below the cost basis is other-than-temporary. The primary factors we consider in our determination are the extent and length of time that the fair value of the investment is below our company’s carrying value and the financial condition, operating performance and near-term prospects of the investee, changes in the stock price or valuation subsequent to the balance sheet date, and the impacts of exchange rates, if applicable. If the decline in fair value of an equity or cost method investment is deemed to be other-than-temporary, the cost basis of the security is written down to fair value.
Financial Instruments	Financial Instruments Due to the short maturities of cash and cash equivalents, restricted cash, short-term liquid investments, trade and other receivables, other current assets, accounts payable, accrued liabilities and other accrued and current liabilities, their respective carrying values approximate their respective fair values. For information concerning the fair values of certain of our investments, derivatives and debt, see notes 6 , 7 and 10 , respectively. For information regarding how we arrive at certain of our fair value measurements, see note 8 .
Derivative Instruments	Derivative Instruments All derivative instruments, whether designated as hedging relationships or not, are recorded on the balance sheet at fair value. If the derivative instrument is not designated as a hedge, changes in the fair value of the derivative instrument are recognized in earnings. If the derivative instrument is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative instrument are recorded in other comprehensive earnings or loss and subsequently reclassified into our consolidated statements of operations when the hedged forecasted transaction affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings. With the exception of a limited number of our foreign currency forward contracts, we do not apply hedge accounting to our derivative instruments. The net cash received or paid related to our derivative instruments is classified as an operating, investing or financing activity in our 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 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 in our consolidated statement of cash flows. For information regarding our derivative instruments, see note 7
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation. We capitalize costs associated with the construction of new cable and mobile transmission and distribution facilities and the installation of new cable services. Capitalized construction and installation costs include materials, labor and other directly attributable costs. Installation activities that are capitalized include (i) the initial connection (or drop) from our cable system to a customer location, (ii) the replacement of a drop and (iii) the installation of equipment for additional services, such as digital cable, telephone or broadband internet service. The costs of other customer-facing activities, such as reconnecting customer locations where a drop already exists, disconnecting customer locations and repairing or maintaining drops, are expensed as incurred. Interest capitalized with respect to construction activities was not material during any of the periods presented. Capitalized internal-use software is included as a component of property and equipment. We capitalize internal and external costs directly associated with the development of internal-use software. We also capitalize costs associated with the purchase of software licenses. Maintenance and training costs, as well as costs incurred during the preliminary stage of an internal-use software development project, are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful life of the underlying asset. Equipment under capital leases is amortized on a straight-line basis over the shorter of the lease term or estimated useful life of the asset. Useful lives used to depreciate our property and equipment are assessed periodically and are adjusted when warranted. The useful lives of cable and mobile distribution systems that are undergoing a rebuild are adjusted such that property and equipment to be retired will be fully depreciated by the time the rebuild is completed. For additional information regarding the useful lives of our property and equipment, see note 9 . Additions, replacements and improvements that extend the asset life are capitalized. Repairs and maintenance are charged to operations. We recognize a liability for asset retirement obligations in the period in which it is incurred if sufficient information is available to make a reasonable estimate of fair values. Asset retirement obligations may arise from the loss of rights of way that we obtain from local municipalities or other relevant authorities. Under certain circumstances, the authorities could require us to remove our network equipment from an area if, for example, we were to discontinue using the equipment for an extended period of time or the authorities were to decide not to renew our access rights. However, because the rights of way are integral to our ability to deliver broadband communications services to our customers, we expect to conduct our business in a manner that will allow us to maintain these rights for the foreseeable future. In addition, we have no reason to believe that the authorities will not renew our rights of way and, historically, renewals have been granted. We also have obligations in lease agreements to restore the property to its original condition or remove our property at the end of the lease term. Sufficient information is not available to estimate the fair value of our asset retirement obligations in certain of our lease arrangements. This is the case for long-term lease arrangements in which the underlying leased property is integral to our operations, there is not an acceptable alternative to the leased property and we have the ability to indefinitely renew the lease. Accordingly, for most of our rights of way and certain lease agreements, the possibility is remote that we will incur significant removal costs in the foreseeable future and, as such, we do not have sufficient information to make a reasonable estimate of fair value for these asset retirement obligations. As of December 31, 2016 and 2015 , the recorded value of our asset retirement obligations was $96.3 million and $63.9 million , respectively.
Intangible Assets	Intangible Assets Our primary intangible assets relate to goodwill, customer relationships and cable television franchise rights. Goodwill represents the excess purchase price over the fair value of the identifiable net assets acquired in a business combination. Customer relationships and cable television franchise rights are initially recorded at their fair values in connection with business combinations. Goodwill and other intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually. Intangible assets with finite lives are amortized on a straight-line basis over their respective estimated useful lives to their estimated residual values, and reviewed for impairment. We do not amortize our cable television franchise rights and certain other intangible assets as these assets have indefinite lives. For additional information regarding the useful lives of our intangible assets, see note 9
Impairment of Property and Equipment and Intangible Assets	Impairment of Property and Equipment and Intangible Assets When circumstances warrant, we review the carrying amounts of our property and equipment and our intangible assets (other than goodwill and other indefinite-lived intangible assets) to determine whether such carrying amounts continue to be recoverable. Such changes in circumstance may include (i) an expectation of a sale or disposal of a long-lived asset or asset group, (ii) adverse changes in market or competitive conditions, (iii) an adverse change in legal factors or business climate in the markets in which we operate and (iv) operating or cash flow losses. For purposes of impairment testing, long-lived assets are grouped at the lowest level for which cash flows are largely independent of other assets and liabilities, generally at or below the reporting unit level (see below). If the carrying amount of the asset or asset group is greater than the expected undiscounted cash flows to be generated by such asset or asset group, an impairment adjustment is recognized. Such adjustment is measured by the amount that the carrying value of such asset or asset group exceeds its fair value. We generally measure fair value by considering (a) sale prices for similar assets, (b) discounted estimated future cash flows using an appropriate discount rate and/or (c) estimated replacement cost. Assets to be disposed of are recorded at the lower of their carrying amount or fair value less costs to sell.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts and income tax basis of assets and liabilities and the expected benefits of utilizing net operating loss and tax credit carryforwards, using enacted tax rates in effect for each taxing jurisdiction in which we operate for the year in which those temporary differences are expected to be recovered or settled. We recognize the financial statement effects of a tax position when it is more-likely-than-not, based on technical merits, that the position will be sustained upon examination. Net deferred tax assets are then reduced by a valuation allowance if we believe it is more-likely-than-not such net deferred tax assets will not be realized. Certain of our valuation allowances and tax uncertainties are associated with entities that we acquired in business combinations. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. Deferred tax liabilities related to investments in foreign subsidiaries and foreign corporate joint ventures that are essentially permanent in duration are not recognized until it becomes apparent that such amounts will reverse in the foreseeable future. In order to be considered essentially permanent in duration, sufficient evidence must indicate that the foreign subsidiary has invested or will invest its undistributed earnings indefinitely, or that earnings will be remitted in a tax-free liquidation. Interest and penalties related to income tax liabilities are included in income tax benefit or expense in our consolidated statements of operations. For additional information on our income taxes, see note 11 .
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions The reporting currency of our company is the U.S. dollar. The functional currency of our foreign operations generally is the applicable local currency for each foreign subsidiary and equity method investee. Assets and liabilities of foreign subsidiaries (including intercompany balances for which settlement is not anticipated in the foreseeable future) are translated at the spot rate in effect at the applicable reporting date. With the exception of certain material transactions, the amounts reported in our consolidated statements of operations are translated at the average exchange rates in effect during the applicable period. The resulting unrealized cumulative translation adjustment, net of applicable income taxes, is recorded as a component of accumulated other comprehensive earnings or loss in our consolidated statements of equity. With the exception of certain material transactions, the cash flows from our operations in foreign countries are translated at the average rate for the applicable period in our consolidated statements of cash flows. The impacts of material transactions generally are recorded at the applicable spot rates in our consolidated statements of operations and cash flows. The effect of exchange rates on cash balances held in foreign currencies are separately reported in our consolidated statements of cash flows.
Revenue Recognition	Revenue Recognition Service Revenue — Cable Networks. We recognize revenue from the provision of video, broadband internet and fixed-line telephony services over our cable network to customers in the period the related services are provided. Installation revenue (including reconnect fees) related to services provided over our cable network is recognized as revenue in the period during which the installation occurs to the extent these fees are equal to or less than direct selling costs, which costs are expensed as incurred. To the extent installation revenue exceeds direct selling costs, the excess revenue is deferred and amortized over the average expected subscriber life. Sale of Multiple Products and Services. We sell video, broadband internet, fixed-line telephony and, in most of our markets, mobile services to our customers in bundled packages at a rate lower than if the customer purchased each product on a standalone basis. Revenue from bundled packages generally is allocated proportionally to the individual services based on the relative standalone price for each respective service. Mobile Revenue — General. Consideration from mobile contracts is allocated to the airtime service element and the handset service element based on the relative standalone prices of each element. The amount of consideration allocated to the handset is limited to the amount that is not contingent upon the delivery of future airtime services. Certain of our operations that provide mobile services offer handsets under a subsidized contract model, whereby upfront revenue recognition is limited to the upfront cash collected from the customer as the remaining monthly fees to be received from the customer, including fees that may be associated with the handset, are contingent upon delivering future airtime services. At certain of our operations, mobile customers may choose to enter into two distinct contractual relationships: (i) a mobile handset contract and (ii) a mobile airtime services contract (a Split-contract Program ). Under the mobile handset contract, the customer takes full title to the handset upon delivery and typically has the option to either (a) pay for the handset in cash upon delivery or (b) pay for the handset in installments over a contractual period. Under these arrangements, the handset installment payments are not contingent upon delivering future airtime services and the consideration allocated to the handset is not limited to the upfront cash collected. Mobile Revenue — Airtime Services. We recognize revenue from mobile services in the period the related services are provided. Revenue from pre-pay customers is recorded as deferred revenue prior to the commencement of services and revenue is recognized as the services are rendered or usage rights expire. Mobile Revenue — Handset Revenue. Arrangement consideration allocated to handsets is recognized as revenue when the goods have been delivered and title has passed. For customers under a mobile handset installment contract that is independent of a mobile airtime services contract, revenue is recognized upon delivery only if collectibility is reasonably assured. Our assessment of collectibility is based principally on internal and external credit assessments as well as historical collection information for similar customers. To the extent that collectibility of installment payments from the customer is not reasonably assured upon delivery of the handset, handset revenue is recognized on a cash basis as customer payments are received. B2B Revenue. We defer upfront installation and certain nonrecurring fees received on B2B contracts where we maintain ownership of the installed equipment. The deferred fees are amortized into revenue on a straight-line basis over the term of the arrangement or the expected period of performance. Promotional Discounts. For subscriber promotions, such as discounted or free services during an introductory period, revenue is recognized only to the extent of the discounted monthly fees charged to the subscriber, if any. Subscriber Advance Payments and Deposits. Payments received in advance for the services we provide are deferred and recognized as revenue when the associated services are provided. Sales, Use and Other Value-Added Taxes ( VAT ).
Share-based Compensation	Share-based Compensation We recognize all share-based payments to employees, including grants of employee share-based incentive awards, based on their grant-date fair values and our estimates of forfeitures. We recognize the grant-date fair value of outstanding awards as a charge to operations over the vesting period. The cash benefits of tax deductions in excess of deferred taxes on recognized share-based compensation expense are reported as a financing cash flow. Payroll taxes incurred in connection with the vesting or exercise of our share-based incentive awards are recorded as a component of share-based compensation expense in our consolidated statements of operations. We use the straight-line method to recognize share-based compensation expense for our outstanding share awards that do not contain a performance condition and the accelerated expense attribution method for our outstanding share awards that contain a performance condition and vest on a graded basis. The grant date fair values for options, share appreciation rights ( SAR s ) and performance-based share appreciation rights ( PSAR s ) are estimated using the Black-Scholes option pricing model, and the grant date fair values for restricted share units ( RSU s ) and performance-based restricted share units ( PSU s) are based upon the closing share price of Liberty Global ordinary shares on the date of grant. We calculate the expected life of options and SAR s granted by Liberty Global to employees based on historical exercise trends. The expected volatility for options and SAR s related to Liberty Global Shares is generally based on a combination of (i) historical volatilities of Liberty Global Shares for a period equal to the expected average life of the awards and (ii) volatilities implied from publicly-traded options for Liberty Global Shares . The expected volatility for options and SARs related to LiLAC Shares is generally based on a combination of (a) historical volatilities of LiLAC Shares for a period equal to the expected average life of the award and, if this data is unavailable, historical volatilities of ordinary shares of a relevant peer group for a period equal to the expected average life of the award, and (b) volatilities implied from publicly-traded options for LiLAC Shares where available. We generally issue new Liberty Global ordinary shares when Liberty Global options or SAR s are exercised and when RSU s and PSU s vest. Although we repurchase Liberty Global ordinary shares from time to time, the parameters of our share purchase and redemption activities are not established solely with reference to the dilutive impact of our share-based compensation plans. For additional information regarding our share-based compensation, see note 13
Litigation Costs	Litigation Costs
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 shares outstanding for the period. Diluted earnings or loss per share presents the dilutive effect, if any, on a per share basis of potential shares (e.g., options, SAR s, PSAR s, RSU
Recent Accounting Pronouncements	Accounting Changes In April 2015, the Financial Accounting Standards Board ( FASB ) issued Accounting Standards Update ( ASU ) No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ( ASU 2015-03 ), which requires debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a reduction of debt, similar to the presentation of debt discounts. For public entities, ASU 2015-03 was effective for annual reporting periods beginning after December 15, 2015. We adopted ASU 2015-03 on January 1, 2016 and, accordingly, deferred financing costs are presented as a reduction of debt in our December 31, 2016 and 2015 consolidated balance sheets. Prior to the adoption of ASU 2015-03 , we presented deferred financing costs in other assets, net. Recent Accounting Pronouncements ASU 2014-09 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ( ASU 2014-09 ), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 , as amended by ASU No. 2015-14, will replace existing revenue recognition guidance when it becomes effective for annual and interim reporting periods beginning after December 15, 2017. This new standard permits the use of either the retrospective or cumulative effect transition method. We will adopt ASU 2014-09 effective January 1, 2018 using the cumulative effect transition method. While we are continuing to evaluate the effect that ASU 2014-09 will have on our consolidated financial statements, we have identified a number of our current revenue recognition policies that will be impacted by ASU 2014-09 , including the accounting for (i) time-limited discounts and free periods provided to our customers and (ii) certain up-front fees charged to our customers. These impacts are discussed below: • When we enter into contracts to provide services to our customers, we often provide time-limited discounts or free service periods. Under current accounting rules, we recognize revenue net of discounts during the promotional periods and do not recognize any revenue during free service periods. Under ASU 2014-09 , revenue recognition will be accelerated for these contracts as the impact of the discount or free service period will be recognized uniformly over the total contractual period. • When we enter into contracts to provide services to our customers, we often charge installation or other up-front fees. Under current accounting rules, installation fees related to services provided over our cable networks are recognized as revenue in the period during which the installation occurs to the extent these fees are equal to or less than direct selling costs. Under ASU 2014-09 , these fees will generally be deferred and recognized as revenue over the contractual period, or longer if the up-front fee results in a material renewal right. As the above revenue recognition changes have offsetting impacts and both result in a relatively minor shift in the timing of revenue recognition, we currently do not expect ASU 2014-09 to have a material impact on our reported revenue. ASU 2014-09 will also impact our accounting for certain upfront costs directly associated with obtaining and fulfilling customer contracts. Under our current policy, these costs are expensed as incurred unless the costs are in the scope of another accounting topic that allows for capitalization. Under ASU 2014-09 , the upfront costs that are currently expensed as incurred will be recognized as assets and amortized to other operating expenses over a period that is consistent with the transfer to the customers of the goods or services to which the assets relate, which we have generally interpreted to be the expected customer life. The impact of the accounting change for these costs will be dependent on numerous factors, including the number of new subscriber contracts added in any given period, but we expect the adoption of this accounting change will initially result in the deferral of a significant amount of operating and selling costs. The ultimate impact of adopting ASU 2014-09 for both revenue recognition and costs to obtain and fulfill contracts will depend on the promotions and offers in place during the period leading up to and after the adoption of ASU 2014-09 . ASU 2016-02 In February 2016, the FASB issued ASU No. 2016-02, Leases ( ASU 2016-02 ), which, for most leases, will result in lessees recognizing lease assets and lease liabilities on the balance sheet with additional disclosures about leasing arrangements. ASU 2016-02 requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach also includes a number of optional practical expedients an entity may elect to apply. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Although we are currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements, we expect the adoption of this standard will increase the number of leases to be accounted for as capital leases in our consolidated balance sheet. ASU 2016-09 In March 2016, the FASB issued ASU No. 2016-09, Compensation — Stock Compensation, Improvements to Employee Share-Based Payment Accounting ( ASU 2016-09 ), which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification within the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those fiscal years, with early adoption permitted. ASU 2016-09 will result in, among other matters, the immediate recognition for financial reporting purposes of excess tax benefits that currently are not recognized until such time as these tax benefits can be realized as a reduction of income taxes payable. ASU 2017-04 In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment ( ASU 2017-04 ), which eliminates the requirement to estimate the implied fair value of a reporting unit’s goodwill as determined following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, a company should recognize any goodwill impairment by comparing the fair value of a reporting unit to its carrying amount. ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We expect the adoption of ASU 2017-04

(b) We consider credit risk in our fair value assessments. As of December 31, 2016 and 2015 , (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 $93.1 million and $64.0 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 $71.5 million and $86.5 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 $16.4 million , $9.3 million and $120.9 million during 2016 , 2015 and 2014 , respectively. These amounts are included in realized and unrealized gains on derivative instruments, net, in our consolidated statements of operations. For further information regarding our fair value measurements, see note 8 . (c) Our equity-related derivative instruments primarily include the fair value of (i) the ITV Collar (ii) the share collar with respect to the shares of Sumitomo held by our company (the Sumitomo Collar ), (iii) the Lionsgate Forward and (iv) at December 31, 2015, Virgin Media ’s conversion hedges with respect to Virgin Media ’s 6.50% convertible senior notes (the Virgin Media Capped Calls ). The fair values of the ITV Collar , the Sumitomo Collar and the Lionsgate Forward do not include credit risk valuation adjustments as we assume that any losses incurred by our company in the event of nonperformance by the respective counterparty would be, subject to relevant insolvency laws, fully offset against amounts we owe to such counterparty pursuant to the related secured borrowing arrangements.

Summary of stock-based compensation	A summary of the aggregate share-based compensation expense that is included in our other operating and SG&A expenses is set forth below: Year ended December 31, 2016 2015 2014 in millions Liberty Global: Performance-based incentive awards (a) $ 162.7 $ 157.1 $ 129.9 Other share-based incentive awards 114.9 149.6 99.7 Total Liberty Global (b) 277.6 306.7 229.6 Telenet share-based incentive awards (c) 12.2 9.2 14.6 Other 7.1 2.3 13.0 Total $ 296.9 $ 318.2 $ 257.2 Included in: Other operating expense: Liberty Global Group $ 3.3 $ 3.1 $ 4.8 LiLAC Group 1.4 0.3 2.8 Total other operating expense 4.7 3.4 7.6 SG&A expense: Liberty Global Group 278.2 312.7 240.8 LiLAC Group 14.0 2.1 8.8 Total SG&A expense 292.2 314.8 249.6 Total $ 296.9 $ 318.2 $ 257.2 _______________ (a) Includes share-based compensation expense related to (i) Liberty Global PSU s, including amounts resulting from the 2016 PSU s, as described and defined below, (ii) a challenge performance award plan for certain executive officers and key employees (the Challenge Performance Awards ) and (iii) PGUs to our Chief Executive Officer, as described below. The Challenge Performance Awards include PSAR s and PSU s. (b) In connection with the LiLAC Transaction , our compensation committee approved modifications to our outstanding share-based incentive awards (the 2015 Award Modifications ) in accordance with the underlying share-based incentive plans. The objective of our 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 our 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 share-based compensation expense should be recorded as a result of the 2015 Award Modifications , we were 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 2015 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, SAR s 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 2015 Award Modifications had been used.
