Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	(1)Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Liberty Interactive Corporation (formerly known as Liberty Media Corporation) and its controlled subsidiaries (collectively, "Liberty" or the "Company" unless the context otherwise requires). All significant intercompany accounts and transactions have been eliminated in consolidation.
	Liberty, through its ownership of interests in subsidiaries and other companies, is primarily engaged in the video and on-line commerce industries in North America, Europe and Asia.
	As further discussed in note 5, on August 27, 2014, Liberty completed the spin-off to holders of its Liberty Ventures common stock shares of its former wholly-owned subsidiary, Liberty TripAdvisor Holdings, Inc. (“TripAdvisor Holdings”) (the “TripAdvisor Holdings Spin-Off”). TripAdvisor Holdings is comprised of Liberty’s former 22% economic and 57% voting interest in TripAdvisor, Inc. (“TripAdvisor”) as well as BuySeasons, Inc. (“BuySeasons”), Liberty’s former wholly-owned subsidiary, and a corporate level net debt balance of $350 million. In connection with the TripAdvisor Holdings Spin-Off during August 2014, TripAdvisor Holdings drew down $400 million in margin loans and distributed approximately $350 million to Liberty. This transaction has been recorded at historical cost due to the pro rata nature of the distribution. Following the completion of the TripAdvisor Holdings Spin-Off, Liberty and TripAdvisor Holdings operate as separate, publicly traded companies, and neither has any stock ownership, beneficial or otherwise, in the other. The consolidated financial statements of Liberty have been prepared to reflect TripAdvisor Holdings as discontinued operations. Accordingly, the assets and liabilities, revenue, costs and expenses, and cash flows of the businesses, assets and liabilities owned by TripAdvisor Holdings at the time of the TripAdvisor Holdings Spin-Off have been excluded from the respective captions in the accompanying consolidated balance sheets, statements of operations, comprehensive earnings (loss) and cash flows in such consolidated financial statements.
	Additionally, on October 3, 2014, Liberty announced that its board of directors approved the change in attribution from the Interactive Group (which we refer to as the QVC Group) to the Ventures Group of its Digital Commerce companies (defined below) and cash. The reattributed Digital Commerce companies are comprised of Liberty’s subsidiaries Backcountry.com, Inc. (“Backcountry”), Bodybuilding.com, LLC (“Bodybuilding”), CommerceHub, Evite, Inc. (“Evite”), Provide Commerce, Inc. (“Provide”) and LMC Right Start, Inc. (“Right Start”) (collectively, the “Digital Commerce” companies). See note 2 for additional information on the reattribution.
	On December 31, 2014, Liberty announced the closing of the acquisition by FTD Companies, Inc. ("FTD") of Provide (the “FTD Transaction”). Under the terms of the transaction, Liberty received approximately 10.2 million shares of FTD common stock representing approximately 35% of the combined company and approximately $145 million in cash. We recognized a gain of $75 million as a result of this transaction, which is included in the Gains (losses) on transactions, net line item in the consolidated statement of operations. Subsequent to completion of the transaction, Liberty accounts for FTD as an equity-method affiliate based on the ownership level and board representation. The FTD Transaction resulted in a non-cash investing addition of $355 million to the investments in affiliates, accounted for using the equity method line item within the consolidated balance sheets. Given our significant continuing involvement with FTD, Provide is not presented as a discontinued operation in the consolidated financial statements of Liberty. As of December 31, 2013, the assets and liabilities subject to the sale are comprised of the following (amounts in millions):
		December 31,
		2013
	Current assets	$	87
	Property & equipment, net	$	32
	Goodwill	$	338
	Trademarks	$	22
	Other intangible assets, net	$	31
	Other assets	$	13
	Current liabilities	$	91
	Net deferred tax liability	$	8
	Other liabilities	$	9
	These net assets are not deemed material for isolated presentation as assets and liabilities held for sale in our consolidated balance sheet as of December 31, 2013. Accordingly, these net assets are included in the above captions in the consolidated balance sheet as of December 31, 2013.
	On September 23, 2011, Liberty completed the split-off of a wholly owned subsidiary, Liberty Media Corporation ("LMC") (formerly known as Liberty CapStarz, Inc. and prior thereto known as Liberty Splitco, Inc.) (the "LMC Split-Off").  Prior to the LMC Split-Off, Liberty's equity was structured into three separate tracking stocks, Liberty Interactive common stock, Liberty Starz common stock and Liberty Capital common stock, which were intended to track and reflect the economic performance of the separate businesses, assets and liabilities attributed to each group.  These attributed businesses, assets and liabilities were not separate legal entities and therefore no group could own assets, issue securities or enter into legally binding agreements.  Holders of the tracking stocks did not have direct claim to the group's stock or assets and were not represented by separate boards of directors. At the time of the LMC Split-Off, LMC owned all the assets, businesses and liabilities previously attributed to the Liberty Capital and Liberty Starz tracking stock groups.  The LMC Split-Off was effected by means of a redemption of all of the Liberty Capital common stock and Liberty Starz common stock of Liberty in exchange for the common stock of LMC.  This transaction was accounted for at historical cost due to the pro rata nature of the distribution.
	Following the LMC Split-Off, Liberty and LMC operate as separate, publicly traded companies, and neither has any stock ownership, beneficial or otherwise, in the other.  In connection with the LMC Split-Off, Liberty and LMC entered into certain agreements in order to govern certain of the ongoing relationships between the two companies after the LMC Split-Off and to provide for an orderly transition. These agreements include a Reorganization Agreement, a Services Agreement, a Facilities Sharing Agreement and a Tax Sharing Agreement.
	The Tax Sharing Agreement provides for the allocation and indemnification of tax liabilities and benefits between Liberty and LMC and other agreements related to tax matters.  Liberty is party to on-going discussions with the IRS under the Compliance Assurance Process audit program.  The IRS may propose adjustments that relate to tax attributes allocated to and income allocable to LMC in the LMC Split-Off.  Any potential outcome associated with any proposed adjustments would be covered by the Tax Sharing Agreement and are not expected to have any impact on Liberty's financial position.  Pursuant to the Services Agreement, LMC will provide Liberty with  general and administrative services including legal, tax, accounting, treasury and investor relations support. Liberty will reimburse LMC for direct, out-of-pocket expenses incurred by LMC in providing these services and for Liberty's allocable portion of costs associated with any shared services or personnel based on an estimated percentage of time spent providing services to Liberty. Under the Facilities Sharing Agreement, Liberty will share office space with LMC and related amenities at LMC's corporate headquarters.  Under these various agreements approximately $11 million, $15 million and $12 million of these allocated expenses were reimbursed from Liberty to LMC for the years ended December 31, 2014, 2013 and 2012, respectively.

Tracking Stock [Abstract]
Tracking Stocks	(2)  Tracking Stocks
	On August 9, 2012 Liberty completed the approved recapitalization of its common stock through the creation of the Liberty Interactive common stock and Liberty Ventures common stock as tracking stocks.  In the recapitalization, each holder of Liberty Interactive Corporation common stock remained a holder of the same amount and series of Liberty Interactive common stock and received 0.05 of a share of the corresponding series of Liberty Ventures common stock, by means of a dividend, with cash issued in lieu of fractional shares of Liberty Ventures common stock.
	At the time of issuance of the Liberty Ventures common stock, cash of $1,346 million was reattributed to the Ventures Group from the QVC Group.  The QVC Group borrowed funds under QVC's credit facility just prior to the completion of the recapitalization in order for Liberty to have an appropriate amount of cash available to be attributed to each tracking stock group.  The reattribution of cash between the tracking stock groups had no consolidated impact on Liberty.
	On February 27, 2014, Liberty's board approved a two for one stock split of Series A and Series B Liberty Ventures common stock, effected by means of a dividend. The stock split was done in order to bring Liberty into compliance with a Nasdaq listing requirement regarding the minimum number of publicly held shares of the Series B Liberty Ventures common stock. In the stock split, a dividend was paid on April 11, 2014 of one share of Series A or Series B Liberty Ventures common stock to holders of each share of Series A or Series B Liberty Ventures common stock, respectively, held by them as of 5:00 pm, New York City time, on April 4, 2014. The stock split has been recorded retroactively for all periods presented for comparability purposes.
	As discussed in note 1, on October 3, 2014, Liberty announced that its board of directors approved the change in attribution from the QVC Group to the Ventures Group its Digital Commerce companies and cash, which was provided by QVC as a result of a draw-down of QVC’s credit facility. The reattribution of the Digital Commerce companies is presented on a prospective basis from the date of the reattribution in Liberty’s consolidated financial statements and attributed financial information, with October 1, 2014 used as a proxy for the date of the reattribution.
	In exchange for the Digital Commerce companies and $970 million of cash (collectively, the "Reattributed Assets"), an inter-group interest in the Ventures Group was created in favor of the QVC Group. This inter-group interest was represented as a number of shares of Liberty Ventures common stock issuable to the QVC Group, which we refer to as the "Inter-Group Interest Shares" (as calculated below). Immediately following the reattribution on October 3, 2014, Liberty's board declared a dividend of the Inter-Group Interest Shares to the holders of Series A and Series B Liberty Interactive common stock in full elimination of the inter-group interest. In connection with the payment of the dividend, typical antidilution adjustments were made to outstanding options of Liberty Interactive common stock equity incentive awards, and the Liberty board has reattributed cash commensurate with the fair value of options assumed (outside of the Reattributed Assets) to the Ventures Group relating to its assumption of liabilities related to those awards.
	In the dividend, the Inter-Group Interest Shares were allocated, pro-rata, to the outstanding shares of Series A and Series B Liberty Interactive common stock at 5:00 p.m., New York City time, on October 13, 2014, the record date for the dividend, such that each holder of Liberty Interactive common stock received 0.14217 of a share of the corresponding series of Liberty Ventures common stock for each share of Liberty Interactive common stock held as of the record date, with cash paid in lieu of fractional shares. The distribution date for the dividend was on October 20, 2014, and the Liberty Interactive common stock began trading ex-dividend on October 15, 2014.  The distribution resulted in 67,671,232 shares of combined Series A and Series B Liberty Ventures common stock being issued. The Inter-Group Interest Shares were allocated such that the number of shares of Series A Liberty Ventures common stock and shares of Series B Liberty Ventures common stock issued in the dividend were in the same proportion as the shares of Series A Liberty Interactive common stock and Series B Liberty Interactive common stock outstanding on the record date, with each share of Series A Liberty Interactive common stock and each share of Series B Liberty Interactive common stock receiving the same fraction of a share of Series A or Series B Liberty Ventures common stock, as the case may be.
	In connection with the reattribution, the Liberty Interactive tracking stock trading symbol “LINTA” was changed to "QVCA" and the "LINTB" trading symbol to "QVCB," effective October 7, 2014. Other than the issuance of Liberty Ventures shares in the fourth quarter of 2014, the reattribution of tracking stock groups has no consolidated impact on Liberty.
	Tracking stock is a type of common stock that the issuing company intends to reflect or "track" the economic performance of a particular business or "group," rather than the economic performance of the company as a whole. Liberty has two tracking stocks—Liberty Interactive common stock and Liberty Ventures common stock, which are intended to track and reflect the economic performance of the QVC Group and Ventures Group, respectively. While the QVC Group and the Ventures Group have separate collections of businesses, assets and liabilities attributed to them, no group is a separate legal entity and therefore cannot own assets, issue securities or enter into legally binding agreements. Holders of tracking stock have no direct claim to the group's stock or assets and are not represented by separate boards of directors. Instead, holders of tracking stock are stockholders of the parent corporation, with a single board of directors and subject to all of the risks and liabilities of the parent corporation.
	The term "Ventures Group" does not represent a separate legal entity, rather it represents those businesses, assets and liabilities that have been attributed to that group.  Following the reattribution, the Ventures Group is comprised primarily of our interests in Expedia, Inc., Interval Leisure Group, Inc., LendingTree, our Digital Commerce companies,  investments in Time Warner Inc. and Time Warner Cable Inc., as well as cash in the amount of approximately $1,884 million (at December 31, 2014), including subsidiary cash. The Ventures Group also has attributed to it certain liabilities related to our Exchangeable Debentures and certain deferred tax liabilities. The Ventures Group is primarily focused on the maximization of the value of these investments and investing in new business opportunities.
	The term "QVC Group" does not represent a separate legal entity, rather it represents those businesses, assets and liabilities that have been attributed to that group. The QVC Group is primarily comprised of our merchandise-focused televised-shopping programs, Internet and mobile application businesses. Following the reattribution, the QVC Group has attributed to it the remainder of our businesses and assets, including our wholly-owned subsidiary QVC and our 38% interest in HSN, Inc. as well as cash in the amount of approximately $422 million (at December 31, 2014), including subsidiary cash.
	See Exhibit 99.1 to this Annual Report on Form 10-K for unaudited attributed financial information for Liberty's tracking stock groups.

Summary of Significant Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	(3)  Summary of Significant Accounting Policies
	Cash and Cash Equivalents
	Cash equivalents consist of investments which are readily convertible into cash and have maturities of three months or less at the time of acquisition.
	Receivables
	Receivables are reflected net of an allowance for doubtful accounts and sales returns.   A provision for bad debts is provided as a percentage of accounts receivable based on historical experience and included in selling, general and administrative expense.  A provision for vendor receivables are determined based on an estimate of probable expected losses and included in cost of goods sold. A summary of activity in the allowance for doubtful accounts is as follows:
			Balance			Additions				Balance
			beginning			Charged			Deductions-	end of
			of year			to expense		Other	write-offs	year
			amounts in millions
	2014		$	86		95		-2	-87	92
	2013		$	76		81		1	-72	86
	2012		$	80		76		—	-80	76
	Inventory
	Inventory, consisting primarily of products held for sale, is stated at the lower of cost or market.  Cost is determined by the average cost method, which approximates the first-in, first-out method.  Assessments about the realizability of inventory require the Company to make judgments based on currently available information about the likely method of disposition including sales to individual customers, returns to product vendors, liquidations and the estimated recoverable values of each disposition category.  Inventory is stated net of inventory obsolescence reserves of $86 million and $88 million for the years ended December 31, 2014 and 2013, respectively.
	Investments
	All marketable equity and debt securities held by the Company are classified as available-for-sale ("AFS") and are carried at fair value generally based on quoted market prices.  U.S. generally accepted accounting principles ("GAAP") permit entities to choose to measure many financial instruments, such as AFS securities, and certain other items at fair value and to recognize the changes in fair value of such instruments in the entity's statement of operations (the "fair value option").  Liberty had previously entered into economic hedges for certain of its non-strategic AFS securities (although such instruments were not accounted for as fair value hedges by the Company).  Changes in the fair value of these economic hedges were reflected in Liberty's statement of operations as unrealized gains (losses).  In order to better match the changes in fair value of the subject AFS securities and the changes in fair value of the corresponding economic hedges in the Company's financial statements, Liberty has elected the fair value option for those of its AFS securities which it considers to be non-strategic ("Fair Value Option Securities").  Accordingly, changes in the fair value of Fair Value Option Securities, as determined by quoted market prices, are reported in realized and unrealized gains (losses) on financial instruments in the accompanying consolidated statement of operations.  The total value of AFS securities for which the Company has elected the fair value option aggregated $1,220 million and $1,309 million as of December 31, 2014 and 2013, respectively.
	Other investments in which the Company's ownership interest is less than 20%, unless the Company has the ability to exercise significant influence, and that are not considered marketable securities are carried at cost.
	For those investments in affiliates in which the Company has the ability to exercise significant influence, the equity method of accounting is used.  Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company's share of net earnings or losses of the affiliate as they occur rather than as dividends or other distributions are received.  Losses are limited to the extent of the Company's investment in, advances to and commitments for the investee.  In the event the Company is unable to obtain accurate financial information from an equity affiliate in a timely manner, the Company records its share of earnings or losses of such affiliate on a lag (see note 8).  The Company's share of net earnings or loss of affiliates also includes any other than temporary declines in fair value recognized during the period.
	Changes in the Company's proportionate share of the underlying equity of an equity method investee, which result from the issuance of additional equity securities by such equity investee, are recognized in the statement of operations through the other, net line item.  To the extent there is a difference between our ownership percentage in the underlying equity of an equity method investee and our carrying value, such difference is accounted for as if the equity method investee were a consolidated subsidiary.
	The Company continually reviews its equity investments and its AFS securities which are not Fair Value Option Securities to determine whether a decline in fair value below the carrying value is other than temporary.  The primary factors the Company considers in its determination are the length of time that the fair value of the investment is below the Company's carrying value; the severity of the decline; and the financial condition, operating performance and near term prospects of the investee.  In addition, the Company considers the reason for the decline in fair value, be it general market conditions, industry specific or investee specific; analysts' ratings and estimates of 12 month share price targets for the investee; changes in stock price or valuation subsequent to the balance sheet date; and the Company's intent and ability to hold the investment for a period of time sufficient to allow for a recovery in fair value.  If the decline in fair value is deemed to be other than temporary, the carrying value of the security is written down to fair value.  In situations where the fair value of an investment is not evident due to a lack of a public market price or other factors, the Company uses its best estimates and assumptions to arrive at the estimated fair value of such investment.  The Company's assessment of the foregoing factors involves considerable management judgment and accordingly, actual results may differ materially from the Company's estimates and judgments.  Writedowns for AFS securities which are not Fair Value Option Securities would be included in the consolidated statements of operations as other than temporary declines in fair values of investments.  Writedowns for equity method investments would be included in share of earnings (losses) of affiliates.
	Derivative Instruments and Hedging Activities
	All of the Company's derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value.  If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings.  If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive earnings and are recognized in the statement of operations when the hedged item affects earnings.  Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings.  If the derivative is not designated as a hedge, changes in the fair value of the derivative are recognized in earnings.  The Company has entered into several interest rate swap agreements to mitigate the cash flow risk associated with interest payments related to certain of its variable rate debt.  None of the Company's derivatives are currently designated as hedges.
	The fair value of the Company's derivative instruments are estimated using the Black-Scholes model.  The Black-Scholes model incorporates a number of variables in determining such fair values, including expected volatility of the underlying security and an appropriate discount rate.  The Company obtains volatility rates from pricing services based on the expected volatility of the underlying security over the remaining term of the derivative instrument.  A discount rate is obtained at the inception of the derivative instrument and updated each reporting period in which equity collars are outstanding, based on the Company's estimate of the discount rate at which it could currently settle the derivative instrument.  The Company considered its own credit risk as well as the credit risk of its counterparties in estimating the discount rate.  Management judgment was required in estimating the Black-Scholes variables.
	Property and Equipment
	Property and equipment consisted of the following:
			December 31,			December 31,
			2014			2013
			amounts in millions
	Land		$	205		208
	Buildings and improvements			935		976
	Support equipment			847		940
	Projects in progress			43		77
	Total property and equipment		$	2,030		2,201
	Property and equipment, including significant improvements, is stated at cost. Depreciation is computed using the straight-line method using estimated useful lives of 2 to 15 years for support equipment and 8 to 20 years for buildings and improvements.  Depreciation expense for the years ended December 31, 2014, 2013 and 2012 was $158 million, $147 million and $142 million, respectively.
	Intangible Assets
	Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment upon certain triggering events.  Goodwill and other intangible assets with indefinite useful lives (collectively, "indefinite lived intangible assets") are not amortized, but instead are tested for impairment at least annually.  Our annual impairment assessment of our indefinite-lived intangible assets is performed during the fourth quarter of each year.
	The Company utilizes a qualitative assessment for determining whether step one of the goodwill impairment analysis is necessary.  The accounting guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.  In evaluating goodwill on a qualitative basis the Company reviews the business performance of each reporting unit and evaluates other relevant factors as identified in the relevant accounting guidance to determine whether it was more likely than not that an indicated impairment exists for any of our reporting units. The Company considers whether there are any negative macroeconomic conditions, industry specific conditions, market changes, increased competition, increased costs in doing business, management challenges, the legal environments and how these factors might impact company specific performance in future periods. As part of the analysis the Company also considers fair value determinations for certain reporting units that have been made at various points throughout the current year and prior year for other purposes.
	If a step one test is considered necessary based on the qualitative factors, the Company compares the estimated fair value of a reporting unit to its carrying value. Developing estimates of fair value requires significant judgments, including making assumptions about appropriate discount rates, perpetual growth rates, relevant comparable market multiples, public trading prices and the amount and timing of expected future cash flows. The cash flows employed in Liberty's valuation analyses are based on management's best estimates considering current marketplace factors and risks as well as assumptions of growth rates in future years. There is no assurance that actual results in the future will approximate these forecasts. For those reporting units whose carrying value exceeds the fair value, a second test is required to measure the impairment loss (the "Step 2 Test"). In the Step 2 Test, the fair value (Level 3) of the reporting unit is allocated to all of the assets and liabilities of the reporting unit with any residual value being allocated to goodwill. Any excess of the carrying value of the goodwill over this allocated amount is recorded as an impairment charge.
	The accounting guidance also permits entities to first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. If the qualitative assessment supports that it is more likely than not that the carrying value of the Company’s indefinite-lived intangible assets, other than goodwill, exceeds its fair value, then a quantitative assessment is performed. If the carrying value of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
	Impairment of Long-lived Assets
	The Company periodically reviews the carrying amounts of its property and equipment and its intangible assets (other than goodwill and indefinite-lived intangibles) to determine whether current events or circumstances indicate that such carrying amounts may not be recoverable.  If the carrying amount of the asset group is greater than the expected undiscounted cash flows to be generated by such asset group, including its ultimate disposition, an impairment adjustment is to be recognized.  Such adjustment is measured by the amount that the carrying value of such asset groups exceeds their fair value.  The Company generally measures fair value by considering sale prices for similar asset groups or by discounting estimated future cash flows using an appropriate discount rate.  Considerable management judgment is necessary to estimate the fair value of asset groups.  Accordingly, actual results could vary significantly from such estimates.  Asset groups to be disposed of are carried at the lower of their financial statement carrying amount or fair value less costs to sell.
	Noncontrolling Interests
	The Company reports noncontrolling interests of subsidiaries within equity in the balance sheet and the amount of consolidated net income attributable to the parent and to the noncontrolling interest is presented in the statement of operations.  Also, changes in ownership interests in subsidiaries in which the Company maintains a controlling interest are recorded in equity.
	Foreign Currency Translation
	The functional currency of the Company is the United States (''U.S.'') dollar.  The functional currency of the Company's foreign operations generally is the applicable local currency for each foreign subsidiary.  Assets and liabilities of foreign subsidiaries are translated at the spot rate in effect at the applicable reporting date, and the 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 in stockholders' equity.
	Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise.  Subsequent changes in exchange rates result in transaction gains and losses which are reflected in the accompanying consolidated statements of operations and comprehensive earnings (loss) as unrealized (based on the applicable period-end exchange rate) or realized upon settlement of the transactions.
	Revenue Recognition
	Retail revenue is recognized at the time of delivery to customers.  The revenue for shipments in-transit is recorded as deferred revenue and included in other current liabilities.  Service revenue is recognized when the applicable criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the price is fixed and determinable and collectability is reasonably assured.
	An allowance for returned merchandise is provided as a percentage of sales based on historical experience.  The total reduction in sales due to returns for the years ended December 31, 2014, 2013 and 2012 aggregated $2,123 million, $2,134 million and $2,037 million, respectively.  Sales tax collected from customers on retail sales is recorded on a net basis and is not included in revenue.
	In May 2014, the Financial Accounting Standards Board issued new accounting guidance on revenue from contracts with customers. The new guidance 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. The updated guidance will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either a retrospective or cumulative effect transition method. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its revenue recognition but does not believe that the standard will significantly impact its financial statements and related disclosures.
	Cost of Sales
	Cost of sales primarily includes actual product cost, provision for obsolete inventory, buying allowances received from suppliers, shipping and handling costs and warehouse costs.
	Advertising Costs
	Advertising costs generally are expensed as incurred.  Advertising expense aggregated $271 million, $258 million and $247 million for the years ended December 31, 2014, 2013 and 2012, respectively. Advertising costs are reflected in the Selling, general and administrative expense line item in our consolidated statements of operations.
	Stock-Based Compensation
	As more fully described in note 14, the Company has granted to its directors, employees and employees of its subsidiaries options, restricted stock and stock appreciation rights ("SARs") to purchase shares of Liberty Interactive and/or Liberty Ventures common stock ("Liberty common stock") (collectively, "Awards").  The Company measures the cost of employee services received in exchange for an Award of equity instruments (such as stock options and restricted stock) based on the grant-date fair value of the Award, and recognizes that cost over the period during which the employee is required to provide service (usually the vesting period of the Award).  The Company measures the cost of employee services received in exchange for an Award of liability instruments (such as stock appreciation rights that will be settled in cash) based on the current fair value of the Award, and remeasures the fair value of the Award at each reporting date.
	Stock compensation expense was $108 million, $118 million and $91 million for the years ended December 31, 2014, 2013 and 2012, respectively, included in selling, general and administrative expense in the accompanying consolidated statements of operations.
	Income Taxes
	The Company accounts for income taxes using the asset and liability method.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying value amounts and income tax bases of assets and liabilities and the expected benefits of utilizing net operating loss and tax credit carryforwards.  The deferred tax assets and liabilities are calculated using enacted tax rates in effect for each taxing jurisdiction in which the Company operates for the year in which those temporary differences are expected to be recovered or settled.  Net deferred tax assets are then reduced by a valuation allowance if the Company believes it more likely than not such net deferred tax assets will not be realized.  The effect on deferred tax assets and liabilities of an enacted change in tax rates is recognized in income in the period that includes the enactment date.
	When the tax law requires interest to be paid on an underpayment of income taxes, the Company recognizes interest expense from the first period the interest would begin accruing according to the relevant tax law.  Such interest expense is included in interest expense in the accompanying consolidated statements of operations.  Any accrual of penalties related to underpayment of income taxes on uncertain tax positions is included in other income (expense) in the accompanying consolidated statements of operations.
	Earnings (Loss) Attributable to Liberty Interactive Corporation Stockholders and Earnings (Loss) Per Common Share
	Net earnings (loss) attributable to Liberty stockholders is comprised of the following (amounts in millions):
		Years ended December 31,
		2014			2013		2012
Liberty Interactive Corporation
Net earnings (loss) from continuing operations		NA		NA		-1
Net earnings (loss) from discontinued operations		NA		NA		295
Liberty Interactive
Net earnings (loss) from continuing operations	$	535		455		262
Net earnings (loss) from discontinued operations	$	-15		-17		-50
Liberty Ventures
Net earnings (loss) from continuing operations	$	3		54		281
Net earnings (loss) from discontinued operations	$	14		9		743
Basic earnings (loss) per common share ("EPS") is computed by dividing net earnings (loss) attributable to such common stock by the weighted average number of common shares outstanding for the period. Diluted EPS presents the dilutive effect on a per share basis of potential common shares as if they had been converted at the beginning of the periods presented.
Series A and Series B Liberty Interactive Corporation Common Stock
The basic and diluted EPS calculation for Liberty Interactive Corporation prior to the recapitalization is based on the following weighted average outstanding shares. Excluded from diluted EPS, for the period prior to the recapitalization, are less than a million potential common shares because their inclusion would be antidilutive.

Series A and Series B Liberty Interactive Common Stock
Liberty completed a recapitalization on August 9, 2012, whereby each holder of current Liberty Interactive Corporation common stock became a holder of the same number of Liberty Interactive common stock. EPS for the period from the recapitalization through December 31, 2014, is based on the following weighted average outstanding shares.  Excluded from diluted EPS for the year ended December 31, 2014 are approximately 1 million potential common shares because their inclusion would be antidilutive.

Series A and Series B Liberty Ventures Common Stock
Liberty completed a recapitalization on August 9, 2012, whereby each holder of then-existing Liberty Interactive common stock received 0.05 of a share of the corresponding series of Liberty Ventures common stock, by means of a dividend, with cash paid in lieu of fractional shares of Liberty Ventures common stock.  Additionally, as part of the recapitalization Liberty distributed subscription rights, which were priced at a discount to the market value, to all holders of Liberty Ventures common stock, see further discussion in note 12.  The rights offering, because of the discount, is considered a stock dividend which requires retroactive treatment for prior periods for the weighted average shares outstanding. As discussed in note 2, Liberty completed a two for one stock split on April 11, 2014 on its Series A and Series B Liberty Ventures common stock.  Therefore, all prior period outstanding share amounts have been retroactively adjusted for comparability.
Additionally, as discussed in note 2, on October 3, 2014, Liberty attributed from the QVC Group to the Ventures Group its Digital Commerce companies. In exchange for the Reattributed Assets, Inter-Group Interest Shares in the Ventures Group were created in favor of the QVC Group. Immediately following the reattribution on October 3, 2014, Liberty's board declared a dividend of the Inter-Group Interest Shares to the holders of Series A and Series B Liberty Interactive common stock in full elimination of the inter-group interest. The Inter-Group Interest Shares were allocated, pro-rata, to the outstanding shares of Series A and Series B Liberty Interactive common stock at 5:00 p.m., New York City time, on October 13, 2014, the record date for the dividend, such that each holder of Liberty Interactive common stock received 0.14217 of a share of the corresponding series of Liberty Ventures common stock for each share of Liberty Interactive common stock held as of the record date, with cash paid in lieu of fractional shares. The distribution date for the dividend was on October 20, 2014, and the Liberty Interactive common stock began trading ex-dividend on October 15, 2014. The reattribution of the Digital Commerce companies is presented on a prospective basis from the date of the reattribution in Liberty’s consolidated financial statements, with October 1, 2014 used as a proxy for the date of the reattribution.
EPS for the period from the recapitalization through December 31, 2014, is based on the following weighted average outstanding shares.  Excluded from diluted EPS for the year ended December 31, 2014 are less than a million potential common shares because their inclusion would be antidilutive.

Reclasses and adjustments
Certain prior period amounts have been reclassified for comparability with the current year presentation.
Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.  Actual results could differ from those estimates.  Liberty considers (i) recurring and non-recurring fair value measurements, (ii) accounting for income taxes, (iii) assessments of other-than-temporary declines in fair value of its investments and (iv) estimates of retail-related adjustments and allowances to be its most significant estimates.
Liberty holds investments that are accounted for using the equity method.  Liberty does not control the decision making process or business management practices of these affiliates.  Accordingly, Liberty relies on management of these affiliates to provide it with accurate financial information prepared in accordance with GAAP that Liberty uses in the application of the equity method.  In addition, Liberty relies on audit reports that are provided by the affiliates' independent auditors on the financial statements of such affiliates.  The Company is not aware, however, of any errors in or possible misstatements of the financial information provided by its equity affiliates that would have a material effect on Liberty's consolidated financial statements.

Discontinued Operations	(5)Discontinued Operations
	On August 27, 2014, Liberty completed the TripAdvisor Holdings Spin-Off to holders of its Liberty Ventures common stock shares of its former wholly-owned subsidiary, TripAdvisor Holdings. TripAdvisor Holdings is comprised of Liberty’s former 22% economic and 57% voting interest in TripAdvisor, as well as BuySeasons, Liberty’s former wholly-owned subsidiary, and a corporate level net debt balance of $350 million. In connection with the TripAdvisor Holdings Spin-Off during August 2014, TripAdvisor Holdings drew down $400 million in margin loans and distributed approximately $350 million to Liberty. This transaction has been recorded at historical cost due to the pro rata nature of the distribution. Following the completion of the TripAdvisor Holdings Spin-Off, Liberty and TripAdvisor Holdings operate as separate, publicly traded companies, and neither has any stock ownership, beneficial or otherwise, in the other. The consolidated financial statements of Liberty have been prepared to reflect TripAdvisor Holdings as discontinued operations. Accordingly, the assets and liabilities, revenue, costs and expenses, and cash flows of the businesses, assets and liabilities owned by TripAdvisor Holdings at the time of the TripAdvisor Holdings Spin-Off have been excluded from the respective captions in the accompanying consolidated balance sheets, statements of operations, comprehensive earnings and cash flows in such consolidated financial statements.
	In connection with the TripAdvisor Holdings Spin-off, Liberty and TripAdvisor Holdings entered into a tax sharing agreement (the “Tax Sharing Agreement”). The Tax Sharing Agreement provides for the allocation and indemnification of tax liabilities and benefits between Liberty and TripAdvisor Holdings and other agreements related to tax matters. Among other things, pursuant to the Tax Sharing Agreement, TripAdvisor Holdings has agreed to indemnify Liberty, subject to certain limited exceptions, for losses and taxes resulting from the TripAdvisor Holdings Spin-Off to the extent such losses or taxes result primarily from, individually or in the aggregate, the breach of certain restrictive covenants made by TripAdvisor Holdings (applicable to actions or failures to act by TripAdvisor Holdings and its subsidiaries following the completion of the TripAdvisor Holdings Spin-Off).
	In October 2014, the IRS completed its examination of the TripAdvisor Holdings Spin-Off and notified Liberty that it agreed with the nontaxable characterization of the transaction. Liberty expects to execute a Closing Agreement with the IRS documenting this conclusion during 2015.
	Certain combined financial information for TripAdvisor Holdings, which is included in the discontinued operations line items of the consolidated Liberty balance sheets as of December 31, 2013, is as follows (amounts in millions):

Fair Value Disclosures [Abstract]
Assets And Liabilities Measured At Fair Value	(6)   Assets and Liabilities Measured at Fair Value
	For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes 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, other than quoted market prices included within Level 1, are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.  The Company does not have any recurring assets or liabilities measured at fair value that would be considered Level 3.
	The Company's assets and liabilities measured at fair value are as follows:
		December 31, 2014				December 31, 2013
				Quoted prices			Quoted prices
				in active	Significant		in active	Significant
				markets	other		markets	other
				for identical	observable		for identical	observable

	Debt	$	2,574	—	2,574	2,355	—	2,355
	The majority of the Company's Level 2 financial assets and liabilities are debt instruments with quoted market prices that are not considered to be traded on "active markets," as defined in GAAP. Accordingly, the debt instruments are reported in the foregoing table as Level 2 fair value.
	Realized and Unrealized Gains (Losses) on Financial Instruments
	Realized and unrealized gains (losses) on financial instruments are comprised of changes in the fair value of the following:

Investments In Available-For-Sale Securities And Other Cost Investments
Investments in available-for-sale securities and other cost investments	(7)   Investments in Available-for-Sale Securities and Other Cost Investments
	All marketable equity and debt securities held by the Company are classified as available-for-sale ("AFS") and are carried at fair value generally based on quoted market prices. GAAP permits entities to choose to measure many financial instruments, such as AFS securities, and certain other items at fair value and to recognize the changes in fair value of such instruments in the entity's statement of operations (the "fair value option"). In prior years, Liberty entered into economic hedges for certain of its non-strategic AFS securities (although such instruments were not accounted for as fair value hedges by the Company). Changes in the fair value of these economic hedges were reflected in Liberty's statement of operations as unrealized gains (losses). In order to better match the changes in fair value of the subject AFS securities and the changes in fair value of the corresponding economic hedges in the Company's financial statements, Liberty elected the fair value option for those of its AFS securities which it considers to be non-strategic ("Fair Value Option Securities"). Accordingly, changes in the fair value of Fair Value Option Securities, as determined by quoted market prices, are reported in realized and unrealized gains (losses) on financial instruments in the accompanying consolidated statements of operations.
	Investments in AFS securities, the majority of which are considered Fair Value Option Securities and other cost investments, are summarized as follows:

		-1		Liberty entered into a forward sales contract on 12 million shares of Expedia common stock in March 2012 at a per share forward price of $34.316.  The forward contract was settled in October 2012 for total cash proceeds of $412 million and the 12 million shares of Expedia common stock, previously held as collateral, were released to the counterparty.  In the fourth quarter of 2012, when the forward contract settled, the difference between the fair value of the Expedia shares and the carrying value of the shares ($443 million) was recognized in the gain (loss) on transactions, net line item in the statement of operations. Liberty owns an approximate 18% equity interest and 58% voting interest in Expedia.  Liberty has entered into governance arrangements pursuant to which Mr. Barry Diller, Chairman of the Board and Senior Executive Officer of Expedia, may vote its interests of Expedia, subject to certain limitations.  Additionally, through our governance arrangements with Mr. Diller, we have the right to appoint and have appointed 20% of the members of Expedia's board of directors, which is currently comprised of 10 members.  Therefore, we determined based on these arrangements that we have significant influence and have accounted for the investment as an equity method affiliate.
		-2		During the years ended December 31, 2014, 2013 and 2012, Expedia, Inc. paid dividends aggregating $15 million, $13 million and $23 million, respectively, and HSN, Inc. paid dividends of $22 million and $16 million during the years ended December 31, 2014 and December 31, 2013, respectively, which were recorded as reductions to the investment balances.
		-3		As discussed in note 1, FTD acquired Liberty’s formerly wholly-owned subsidiary, Provide, on December 31, 2014. In exchange for Provide, Liberty received approximately 10.2 million shares of FTD common stock representing approximately 35% of the combined company and approximately $145 million in cash. Subsequent to completion of the transaction, Liberty accounts for FTD as an equity-method affiliate based on the ownership level and board representation.

	The weighted average life of these amortizable intangible assets was approximately 9 years, at the time of acquisition.  However, amortization is expected to match the usage of the related asset and will be on an accelerated basis as demonstrated in table below.
	Amortization expense for intangible assets with finite useful lives was $504 million, $482 million and $449 million for the years ended December 31, 2014, 2013 and  2012, respectively. Based on its amortizable intangible assets as of December 31, 2014, Liberty expects that amortization expense will be as follows for the next five years (amounts in millions):
	2015	$	470
	2016	$	421
	2017	$	262
	2018	$	10
	2019	$	7
	Impairments
	Continued declining operating results as compared to budgeted results and certain trends related to certain Digital Commerce companies required a Step 2 impairment test and a determination of fair value for those subsidiaries.  Fair value for those subsidiaries, including the related intangibles and goodwill, were determined using the respective companies' projections of future operating performance and applying a combination of market multiples (market approach) and discounted cash flow (income approach) calculations (Level 3).  As of December 31, 2014 accumulated goodwill impairment losses for the Digital Commerce companies was $111 million.

	Exchangeable Senior Debentures
	Each $1,000 original principal amount of the 0.75% Exchangeable Senior Debentures is exchangeable for a basket of 6.3040 shares of common stock of Time Warner Cable Inc., 5.1635 shares of common stock of Time Warner Inc. and 0.6454 shares of Time, Inc., which may change over time to include other publicly traded common equity securities that may be distributed on or in respect of those shares of Time Warner Cable Inc. and Time Warner Inc. (or into which any of those securities may be converted or exchanged).  This basket of shares for which each Debenture in the original principal amount of $1,000 may be exchanged is referred to as the Reference Shares attributable to such Debenture, and to each issuer of Reference Shares as a Reference Company. Each Debenture is exchangeable at the option of the holder at any time, upon which they will be entitled to receive the Reference Shares attributable to such Debenture or, at the election of Liberty Interactive LLC (“Liberty LLC”), cash or a combination of Reference Shares and cash having a value equal to such Reference Shares. Upon exchange, holders will not be entitled to any cash payment representing accrued interest or outstanding additional distributions.
	Each $1,000 debenture of Liberty LLC's 4% Exchangeable Senior Debentures is exchangeable at the holder's option for the value of 3.2265 shares of Sprint common stock and 0.7860 shares of CenturyLink, Inc. ("CenturyLink") common stock.  Liberty LLC may, at its election, pay the exchange value in cash, Sprint and CenturyLink common stock or a combination thereof.  Liberty LLC, at its option, may redeem the debentures, in whole or in part, for cash generally equal to the face amount of the debentures plus accrued interest.
	Each $1,000 debenture of Liberty LLC's 3.75% Exchangeable Senior Debentures is exchangeable at the holder's option for the value of 2.3578 shares of Sprint common stock and 0.5746 shares of CenturyLink common stock.  Liberty LLC may, at its election, pay the exchange value in cash, Sprint and CenturyLink common stock or a combination thereof.  Liberty, at its option, may redeem the debentures, in whole or in part, for cash equal to the face amount of the debentures plus accrued interest.
	Each $1,000 debenture of Liberty LLC's 3.5% Exchangeable Senior Debentures (the "Motorola Exchangeables") was exchangeable at the holder's option for the value of 5.2598 shares of Motorola Solutions, Inc. and 4.6024 shares of Motorola Mobility Holdings, Inc., as a result of Motorola Inc.'s separation of Motorola Mobility Holdings, Inc. ("MMI") in a 1 for 8 stock distribution, and the subsequent 1 for 7 reverse stock split of Motorola, Inc. (which has been renamed Motorola Solutions, Inc. ("MSI")), effective January 4, 2011.  MMI was acquired on May 22, 2012 for $40 per share in cash. Pursuant to the indenture, the cash paid to shareholders in the MMI acquisition was to be paid to the holders of the Motorola Exchangeables as an extraordinary distribution.  Liberty LLC made a cash payment of $184.096 per debenture in the second quarter of 2012 for a total payment of $111 million.  The remaining exchange value is payable, at Liberty's option, in cash or MSI stock or a combination thereof.  Liberty LLC, at its option, may redeem the debentures, in whole or in part, for cash generally equal to the adjusted principal amount of the debentures plus accrued interest.  As a result of a cash distribution made by Liberty LLC in 2007, the cash disbursement discussed above and various principal payments made to holders of the Motorola Exchangeables, the adjusted principal amount of each $1,000 debenture is $592, as of December 31, 2014.
	Each $1,000 original principal amount of the 1% Exchangeable Senior Debentures due 2043 (the “HSNi Exchangeables”) is initially exchangeable for 13.4580 shares of common stock of HSNi (the "HSNi Reference Shares"). Each of the HSNi Exchangeables is exchangeable at the option of the holder, for certain triggering events (primarily the increase in an average trading period at the end of the quarter for HSNi reference shares above 130% or below 98% of the adjusted principal amount at the end of a quarter) after the calendar quarter ended March 31, 2014, upon achieving certain trading prices of the underlying HSNi Reference Shares.  Upon exchange, holders of HSNi Exchangeables will be entitled to receive the HSNi Reference Shares attributable to such HSNi Exchangeables or, at the election of Liberty LLC, cash or a combination of HSNi Reference Shares and cash having a value equal to such HSNi Reference Shares. For purposes of the HSNi Exchangeables, Liberty LLC is treated as an affiliate of HSNi under the Securities Act. Therefore, for as long as Liberty LLC is treated as an affiliate of HSNi for purposes of the HSNi Exchangeables, any reference shares consisting of HSNi common stock (or common stock of any other reference company of which Liberty LLC is treated as an affiliate for purposes of the HSNi Exchangeables) delivered by Liberty LLC upon exchange or purchase of a HSNi Exchangeables will be "restricted securities" under the Securities Act and subject to restrictions on transfer. Liberty LLC may deliver HSNi Reference Shares upon exchange or purchase of the HSNi Exchangeables only if (1) permitted under certain contractual arrangements between the Company and HSNi and (2) such Reference Shares would be freely transferable by the holders of the HSNi Reference Shares (other than by affiliates of HSNi) under the Securities Act, or if not freely transferable, there is at that time an effective registration statement under a registration rights agreement that Liberty LLC has with HSNi (or such other Reference Company) pursuant to which the recipients of such HSNi Reference Shares may sell those shares in a registered transaction under the Securities Act.
	Liberty LLC will make an additional distribution on the HSNi Exchangeables if HSNi makes a distribution of cash (an “Excess Regular Cash Dividend”) in excess of the regular quarterly cash dividend of $0.18, currently paid by the HSNi securities (other than publicly traded common equity securities) or other property with respect to the HSNi Reference Shares.  The principal amount of the HSNi Exchangeables will not be reduced by any amount we pay that corresponds to any Excess Regular Cash Dividends on the HSNi Reference Shares.  In January 2015 HSNi declared a special dividend of $10 per share from which Liberty anticipates receiving approximately $200 million in cash in February 2015.  Pursuant to the debentures a portion of the special dividend ($54 million) will be passed through to the holders of the notes and will reduce the outstanding principal balance in March 2015.
	On October 5, 2016, Liberty LLC may, at its option, redeem the HSNi Exchangeables, in whole or in part, in each case at a redemption price, in cash, equal to the adjusted principal amount of the HSNi Exchangeables plus accrued and unpaid interest to the date of redemption plus any final period distribution.  Additionally, as of such date, holders may tender HSNi Exchangeables for purchase by Liberty LLC, at a purchase price equal to the adjusted principal amount plus accrued and unpaid interest to the purchase date plus any final period distribution. Liberty LLC may pay the purchase price, at its election, in cash or through delivery of HSNi Reference Shares (subject to the restrictions discussed previously) having a value equal to the purchase price or a combination of HSNi Reference Shares and cash.  If Liberty LLC makes a partial redemption, HSNi Exchangeables in an aggregate original principal amount of at least $100 million must remain outstanding.
	Liberty has elected to account for all of its Exchangeables using the fair value option. Accordingly, changes in the fair value of this instrument are recognized as unrealized gains (losses) in the statements of operations.  Liberty will review the triggering events on a quarterly basis to determine whether a triggering event has occurred to require current classification of certain Exchangeables, see additional discussion below.
	Liberty has sold, split-off or otherwise disposed of all of its shares of Motorola, Sprint and CenturyLink common stock which underlie the respective Exchangeable Senior Debentures. Because such exchangeable debentures are exchangeable at the option of the holder at any time and Liberty can no longer use owned shares to redeem the debentures, Liberty has classified for financial reporting purposes the portion of the debentures that could be redeemed for cash as a current liability.  Such amount aggregated $910 million at December 31, 2014.  Although such amount has been classified as a current liability for financial reporting purposes, the Company believes the probability that the holders of such instruments will exchange a significant principal amount of the debentures prior to maturity is remote.
	Interest on the Company's exchangeable debentures is payable semi-annually based on the date of issuance.  At maturity, all of the Company's exchangeable debentures are payable in cash.
	Senior Debentures
	Interest on the Senior Debentures is payable semi-annually based on the date of issuance.
	The Senior Debentures are stated net of an aggregate unamortized discount of $5 million at December 31, 2014 and 2013.  Such discount is being amortized to interest expense in the accompanying consolidated statements of operations.
	QVC Senior Secured Notes
	On March 18, 2014, QVC issued $400 million principal amount of new 3.125% Senior Secured Notes due 2019 at an issue price of 99.828% and $600 million principal amount of new 4.85% Senior Secured Notes due 2024 at an issue price of 99.927% (collectively, the “March Notes”). The March Notes are secured by the capital stock of QVC and certain of QVC’s subsidiaries and have equal priority to QVC’s senior secured credit facility. The net proceeds from the March Notes offerings were used to repay indebtedness under QVC’s senior secured credit facility and for working capital and other general corporate purposes.
	On August 21, 2014, QVC issued $600 million principal amount of 4.45% Senior Secured Notes due 2025 at an issue price of 99.860% and new $400 million principal amount 5.45% Senior Secured Notes due 2034 at an issue price of 99.784% (collectively, the “August Notes”). The August Notes are secured by the capital stock of QVC and certain of QVC’s subsidiaries and have equal priority to QVC’s senior secured credit facility. The net proceeds from the August Notes offerings were used for the redemption of QVC’s 7.5% Senior Secured Notes due 2019 (the “Redemption”) on September 9, 2014 and for working capital and other general corporate purposes.
	As a result of the Redemption, QVC incurred an extinguishment loss of $48 million for the year ended December 31, 2014. As a result of refinancing transactions in the prior year, QVC recorded extinguishment losses of $57 million for the year ended December 31, 2013. Losses on early extinguishment of debt are recorded in other, net in the Company's consolidated statements of operations.
	During prior years, QVC issued $500 million principal amount of 7.375% Senior Secured Notes due 2020 at par, $1,000 million principal amount of QVC 7.50% Senior Secured Notes due 2019 at an issue price of 98.278% of par, $500 million principal amount of 5.125% Senior Secured Notes due 2022 at par, $750 million principal amount of 4.375% Senior Secured Notes due 2023 at par and $300 million principal amount of 5.95% Senior Secured Notes due 2043 at par.
	QVC was in compliance with all of its debt covenants related to its outstanding senior notes at December 31, 2014.
	QVC Bank Credit Facilities
	The QVC Bank Credit Facility is a multi-currency facility providing for a $2 billion revolving credit facility, with a $250 million sub-limit for standby letters of credit and $1 billion of uncommitted incremental revolving loan commitments or incremental term loans. The loans are scheduled to mature on March 1, 2018. The Bank Credit Facility contains covenants customary to those generally contained in bank credit facilities. Borrowings under the Bank Credit Facility bear interest at either the alternate base rate or LIBOR (based on an interest period selected by QVC of one week, one month, two months, three months or six months, or to the extent available from all lenders, nine months or twelve months) at QVC's election in each case plus a margin. Borrowings that are alternate base rate loans will bear interest at a per annum rate equal to the base rate plus a margin that varies between 0.25% and 1.00% depending on QVC's ratio of consolidated total debt to consolidated Adjusted OIBDA (the “consolidated leverage ratio”). Borrowings that are LIBOR loans will bear interest at a per annum rate equal to the applicable LIBOR plus a margin that varies between 1.25% and 2.00% depending on QVC's consolidated leverage ratio. The interest rate on the senior secured credit facility was 2.0% at December 31, 2014. Each loan may be prepaid at any time and from time to time without penalty other than customary breakage costs.  Any amounts prepaid on the revolving facility may be reborrowed. The Bank Credit Facility is secured by the stock of QVC. Availability under the QVC Credit Agreement at December 31, 2014 was $1.5 billion. QVC was in compliance with all debt covenants related to the bank Credit Facility at December 31, 2014.
	QVC Interest Rate Swap Arrangements
	In prior years QVC entered into forward interest rate swap arrangements with an aggregate notional amount of $3.1 billion. Such arrangements matured in March 2013 and no further interest swap arrangements were entered into.  These swap arrangements did not qualify as cash flow hedges under GAAP. Accordingly, changes in the fair value of the swaps were reflected in realized and unrealized gains or losses on financial instruments in the accompanying consolidated statements of operations.
	Other Subsidiary Debt
	Other subsidiary debt at December 31, 2014 is comprised of capitalized satellite transponder lease obligations and bank debt of certain subsidiaries.
	Five Year Maturities
The annual principal maturities of Liberty's debt, based on stated maturity dates, for each of the next five years is as follows (amounts in millions):
2015	$	47
2016	$	26
2017	$	39
2018	$	533
2019	$	427
Fair Value of Debt
Liberty estimates the fair value of its debt based on the quoted market prices for the same or similar issues or on the current rate offered to Liberty for debt of the same remaining maturities. The fair value, based on quoted prices of instruments but not considered to be active markets (Level 2), of Liberty's publicly traded debt securities that are not reported at fair value in the accompanying consolidated balance sheets is as follows (amounts in millions):
	December 31,
	2014		2013
Senior debentures	$	882	845
QVC senior secured notes	$	4,118	2,861
Due to the variable rate nature, Liberty believes that the carrying amount of its subsidiary debt not discussed above approximated fair value at December 31, 2014.

	During 2014 and 2013, Liberty changed its estimate of the effective state tax rate used to measure its net deferred tax liabilities, based on expected changes to the Company’s state apportionment factors. The change in 2014 was caused by the sale of a consolidated subsidiary (Provide) on December 31, 2014.  The change in state apportionment factors during 2013 also changed the potential utilization of the Company’s state net operating loss carryforwards, which resulted in a valuation allowance being recorded for certain state net operating loss carryforwards that may expire unused. In both years, the rate change required an adjustment to the recognized deferred taxes at the corporate level. During 2014, 2013 and 2012, Liberty offset federal tax liabilities with tax credits derived from its alternative energy investments.
	The tax effects of temporary differences that give rise to significant portions of the deferred income tax assets and deferred income tax liabilities are presented below:
		December 31,
		2014		2013

Current deferred tax liabilities	$	972	925
Long-term deferred tax liabilities		1,849	2,001
Net deferred tax liabilities	$	2,821	2,926
The Company's valuation allowance increased $2 million in 2014.  The entire change in valuation allowance affected tax expense.
At December 31, 2014, Liberty had net operating losses (on a tax effected basis) and foreign tax credit carryforwards for income tax purposes aggregating approximately $90 million and $88  million, respectively, of which, $9 million will expire in 2017 and $169 million will expire beyond 2020 if not utilized to reduce domestic, state or foreign income tax liabilities in future periods.  These net operating losses and foreign tax credit carryforwards are expected to be utilized prior to expiration, except for $54 million of net operating losses which based on current projections of domestic, state and foreign income may expire unused.
A reconciliation of unrecognized tax benefits is as follows:
	Years ended December 31,
	2014		2013
	amounts in millions
Balance at beginning of year	$	124	122
Additions based on tax positions related to the current year		16	19
Additions for tax positions of prior years		20	1
Reductions for tax positions of prior years		-3	-3
Lapse of statute and settlements		-21	-15
Balance at end of year	$	136	124
As of December 31, 2014, the Company had recorded tax reserves of $136 million related to unrecognized tax benefits for uncertain tax positions.  If such tax benefits were to be recognized for financial statement purposes, $68 million would be reflected in the Company's tax expense and affect its effective tax rate.  Liberty's estimate of its unrecognized tax benefits related to uncertain tax positions requires a high degree of judgment. The Company has tax positions for which the amount of related unrecognized tax benefits could change during 2015. The amount of unrecognized tax benefits related to these issues could change as a result of potential settlements, lapsing of statute of limitations and revisions of estimates.  It is reasonably possible that the amount of the Company's gross unrecognized tax benefits may decrease within the next twelve months by up to $23 million.
As of December 31, 2014, the Company's 2001 through 2010 tax years are closed for federal income tax purposes, and the IRS has completed its examination of the Company's 2010 through 2012 tax years.  The Company's tax loss carryforwards from its 2010 through 2012 tax years are still subject to adjustment.  The Company's 2013 and 2014 tax years are being examined currently as part of the IRS's Compliance Assurance Process ("CAP") program.  Various states are currently examining the Company's prior years state income tax returns.  QVC is currently under audit in the U.K., Germany and Italy.  As of December 31, 2014, no material assessments have resulted from these audits.
As of December 31, 2014, the Company had recorded $28 million of accrued interest and penalties related to uncertain tax positions.

	Chief Executive Officer Compensation Arrangement
	In December 2014, the Compensation Committee (the "Committee") of Liberty approved a compensation arrangement, including term options discussed in note 14, for its President and Chief Executive Officer (the "CEO"). The arrangement provides for a five year employment term beginning January 1, 2015 and ending December 31, 2019, with an annual base salary of $960,750, increasing annually by 5% of the prior year's base salary, and an annual target cash bonus equal to 250% of the applicable year's annual base salary. The arrangement also provides that, in the event the CEO is terminated for "cause," he will be entitled only to his accrued base salary and any amounts due under applicable law and he will forfeit all rights to his unvested term options. If, however, the CEO is terminated by Liberty without cause or if he terminates his employment for “good reason,” the arrangement provides for him to receive his accrued base salary, his accrued but unpaid bonus and any amounts due under applicable law, a severance payment of 1.5 times his base salary during the year of his termination, a payment equal to $11,750,000 pro rated based upon the elapsed number of days in the calendar year of termination, a payment equal to $17.5 million, and for his unvested term options to generally vest pro rata based on the portion of the term elapsed through the termination date plus 18 months and for all vested and accelerated options to remain exercisable until their respective expiration dates. If the CEO terminates his employment without “good reason,” he will be entitled to his accrued base salary, his accrued but unpaid bonus and any amounts due under applicable law and a payment of the $11,750,000 and for his unvested term options to generally vest pro rata based on the portion of the term elapsed through the termination date and all vested and accelerated options to remain exercisable until their respective expiration dates.  Lastly, in the case of the CEO's death or his disability, the arrangement provides that he will be entitled only to his accrued base salary and any amounts due under applicable law, a payment of 1.5 times his base salary during that year, a payment equal to $11,750,000 pro rated based upon the elapsed number of days in the calendar year of termination, a payment equal to $17.5 million and for his unvested term options to fully vest and for his vested and accelerated term options to remain exercisable until their respective expiration dates.
	In addition, beginning in 2015, the CEO will receive annual performance-based options to purchase shares of QVCB and LVNTB with a term of 7 years (the “Performance Options”) and performance-based restricted stock units with respect to QVCB and LVNTB (the “Performance RSUs” and together with the Performance Options, the “Performance Awards”) during the employment term.  Grants of Performance Awards will be allocated between Liberty and Liberty Media Corporation. The aggregate target amount to be allocated between Liberty and Liberty Media will be $16 million with respect to calendar year 2015, $17 million with respect to calendar year 2016, $18 million with respect to calendar year 2017, $19 million with respect to calendar year 2018 and $20 million with respect to calendar year 2019.  Vesting of the Performance Awards will be determined based on satisfaction of performance metrics that will be set by Liberty and Liberty Media’s respective compensation committees in the first quarter of each applicable year, except that the CEO will forfeit his unvested Performance Awards if his employment is terminated for any reason before the end of the applicable year.  In addition, Liberty and Liberty Media’s compensation committees may grant additional Performance Awards, with a value of up to 50% of the target amount allocated to Liberty for the relevant year (the “Above Target Awards”), and the compensation committees may determine to establish additional performance metrics with respect to such Above Target Awards.
	Salary compensation related to services provided is allocated from LMC to Liberty pursuant to the Services Agreement.  Any cash bonus attributable to the performance of Liberty is paid directly by Liberty.

	Liberty - Incentive Plans
	Pursuant to the Liberty Interactive Corporation 2000 Incentive Plan, as amended from time to time (the "2000 Plan"), and  the Liberty Interactive Corporation 2007 Incentive Plan, as amended from time to time (the "2007 Plan") the Company has granted to certain of its employees stock options and SARs (collectively, "Awards") to purchase shares of Liberty common stock. The 2000 Plan and 2007 Plan provide for Awards to be issued in respect of a maximum of 1.9 million shares and 3.5 million shares, respectively, of Liberty common stock.  No additional grants may be made pursuant to these plans.  On June 24, 2010, stockholders of the Company approved the Liberty Interactive Corporation 2010 Incentive Plan, as amended from time to time (the "2010 Plan").  The 2010 Plan provides for Awards to be made in respect of a maximum of 45.6 million shares of Liberty common stock.  Additionally, pursuant to the Liberty Interactive Corporation 2012 Incentive Plan, as amended (the "2012 Plan"), the Company may grant Awards to be made in respect of a maximum of 47 million shares of  Liberty common stock.  Awards generally vest over 4-5 years and have a term of 7-10 years. Liberty issues new shares upon exercise of equity awards.
	Pursuant to the Liberty Interactive Corporation 2011 Nonemployee Director Incentive Plan, as amended from time to time (the "2011 NDIP"), the Liberty Board of Directors has the full power and authority to grant eligible nonemployee directors stock options, SARs, stock options with tandem SARs, and restricted stock.
	In connection with the TripAdvisor Holdings Spin-Off in August 2014, all outstanding Awards with respect to Liberty Ventures common stock (“Liberty Ventures Award”) were adjusted pursuant to the anti-dilution provisions of the incentive plans under which the equity awards were granted, such that a holder of a Liberty Ventures Award received:
		i.		An adjustment to the exercise price or base price, as applicable, and the number of shares subject to the Liberty Ventures Award (as so adjusted, an “Adjusted Liberty Ventures Award”) and
		ii.		A corresponding equity award relating to shares of TripAdvisor Holdings common stock (a “TripAdvisor Holdings Award”)
	The exercise prices and number of shares subject to the Adjusted Liberty Ventures Award and the TripAdvisor Holdings Award were determined based on 1) the exercise prices and number of shares subject to the Liberty Ventures Award, 2) the pre-distribution trading price of the Liberty Ventures common stock and 3) the post-distribution trading prices of Liberty Ventures common stock and TripAdvisor Holdings common stock, such that all of the pre-distribution intrinsic value of the Liberty Ventures Award was allocated between the Adjusted Liberty Ventures Award and the TripAdvisor Holdings Award.
	Following the TripAdvisor Holdings Spin-Off, employees of Liberty hold Awards in both Liberty Ventures common stock and TripAdvisor Holdings common stock.  The compensation expense relating to employees of Liberty is recorded at Liberty.
	Additionally, outstanding stock options, relating to Liberty Interactive common stock, were adjusted, using a similar methodology as described above, in connection with the stock dividend related to the reattribution of the Digital Commerce businesses from the QVC Group to the Ventures Group during October 2014.
	Liberty - Grants
	During the year ended December 31, 2014, Liberty granted, primarily to QVC employees, 1.9 million options to purchase shares of Series A Liberty Interactive common stock which had a weighted average grant-date fair value of $12.04 per share. Liberty also granted approximately 20 thousand options to purchase shares of Series A Liberty Ventures common stock which had a weighted average grant-date fair value of $16.55 per share. Such options primarily vest on a semi-annual basis over a 4 year vesting period.
	In December 2014, Liberty granted 646 thousand options of Series B Liberty Interactive common stock and 1.4 million options of Series B Liberty Ventures common stock to the CEO of Liberty in connection with a new employment agreement (see note 13).  Such options had a weighted average grant-date fair value of $10.50 per share and $15.52 per share, respectively.  Of those options, one half vest on December 24, 2018 and the other half vest on December 24, 2019.
	During the year ended December 31, 2013, Liberty granted, primarily to QVC employees, 4.3 million options to purchase shares of Series A Liberty Interactive common stock.

	During the year ended December 31, 2012, the Company granted approximately 3.4 million options to purchase shares of Series A Liberty Interactive common stock.  Such options had a weighted average grant-date fair value of $8.44.  During the year ended December 31, 2012, the Company also granted 36 thousand options to purchase shares of Series A Liberty Ventures common stock, which options had a weighted average grant-date fair value of $27.29 per share.
	During the fourth quarter of 2012, the Company entered into a series of transactions with certain officers of Liberty and its subsidiaries, associated with certain outstanding stock options, in order to recognize tax deductions in that year versus future years (the "2012 Option Exchange").  On December 4, 2012 (the "Grant Date"), pursuant to the approval of the Compensation Committee of its Board of Directors, the Company effected the acceleration of (i) each unvested in-the-money option to acquire shares of Series A Liberty Interactive common stock and (ii) each unvested in-the-money option to acquire shares of Series A Liberty Ventures common stock, in each case, held by certain of its and its subsidiaries' officers (collectively, the “Eligible Optionholders”). Following this acceleration, also on the Grant Date, each Eligible Optionholder exercised, on a net settled basis, substantially all of his or her outstanding in-the-money vested and unvested options to acquire Series A Liberty Interactive shares and Series A Liberty Ventures shares (the “Eligible Options”), and:
		·		with respect to each vested Eligible Option, the Company granted the Eligible Optionholder a vested new option with substantially the same terms and conditions as the exercised vested Eligible Option;
		·		and with respect to each unvested Eligible Option:
		·		the Eligible Optionholder sold to the Company, for cash, the shares of Series A Liberty Interactive or Series A Liberty Ventures, as applicable, received upon exercise of such unvested Eligible Option and used the proceeds of that sale to purchase from the Company an equal number of restricted Series A Liberty Interactive or Series A Liberty Ventures shares, as applicable, which have a vesting schedule identical to that of the exercised unvested Eligible Option; and
		·		the Company granted the Eligible Optionholder an unvested new option, with substantially the same terms and conditions as the exercised unvested Eligible Option, except that (a) the number of shares underlying the new option is equal to the number of shares underlying such exercised unvested Eligible Option less the number of restricted shares purchased from the Company as described above and (b) the exercise price of the new option is the closing price per Series A Liberty Interactive or Series A Liberty Ventures share, as applicable, on The Nasdaq Global Select Market on the Grant Date.
	In connection with the 2012 Option Exchange, Liberty granted 20.1 million and 905 thousand options to purchase shares of Series A Liberty Interactive common stock and Series A Liberty Ventures common stock, respectively.  Such options had a weighted average grant-date fair value of $7.15 and $26.58 per share, respectively.
	The 2012 Option Exchange was considered a modification under ASC 718 - Stock Compensation and resulted in incremental compensation expense in 2012 of $17 million and $4 million for the Liberty Interactive (now QVC) and Liberty Ventures groups, respectively.  Incremental compensation expense is also being recognized over the remaining vesting periods of the new unvested options and the restricted shares and is included in unrecognized compensation.
	The Company has calculated the grant-date fair value for all of its equity classified awards and any subsequent remeasurement of its liability classified awards using the Black-Scholes Model. The Company estimates the expected term of the Awards based on historical exercise and forfeiture data.  For grants made in 2014, 2013 and 2012, the range of expected terms was 1.3 to 9.0 years.  The volatility used in the calculation for Awards is based on the historical volatility of Liberty's stocks and the implied volatility of publicly traded Liberty options. The Company uses a zero dividend rate and the risk-free rate for Treasury Bonds with a term similar to that of the subject options.
	The following table presents the range of volatilities used by Liberty in the Black-Scholes Model for the 2014, 2013 and 2012 Liberty Interactive and Liberty Ventures grants.
			Volatility
	2014 grants
	Liberty Interactive options		33.6	%	-	39.7	%

	The following table presents the number and weighted average exercise price ("WAEP") of the Awards to purchase Liberty Interactive and Liberty Ventures common stock granted to certain officers, employees and directors of the Company, as well as the weighted average remaining life and aggregate intrinsic value of the Awards.  As discussed in note 2, on February 27, 2014, Liberty’s board approved a two for one stock split of Series A and Series B Liberty Ventures common stock, to be effected by means of a dividend.  The stock split has been recorded retroactively for all periods presented for comparability purposes.

	As of December 31, 2014, the total unrecognized compensation cost related to unvested awards of Liberty employees was approximately $80 million, including incremental compensation under the Option Exchange. Such amount will be recognized in the Company's consolidated statements of operations over a weighted average period of approximately 2.0 years.
Liberty - Exercises
The aggregate intrinsic value of all options exercised during the years ended December 31, 2014, 2013 and 2012 was $91 million, $76 million and $339 million, respectively.  The aggregate intrinsic value of options exercised for the year ended December 31, 2012 includes approximately $242 million related to the intrinsic value of options exercised as a result of the 2012 Option Exchange.
Liberty - Restricted Stock
Associated with the 2012 Option Exchange the Company issued unvested restricted shares of Liberty Interactive and Liberty Ventures common stock, of which 639 thousand and 177 thousand shares, respectively, remain unvested as of December 31, 2014.  These shares continue to vest over the next year, and since the 2012 Option Exchange was accounted for as a modification, the compensation expense associated with these restricted shares was treated as incremental compensation, as discussed above, and is included in the total unrecognized compensation costs under the outstanding Awards section above. The Company had approximately 1.3 million shares and 249 thousand shares of unvested restricted Liberty Interactive and Liberty Ventures common stock, respectively, held by certain directors, officers and employees of the Company as of December 31, 2014, not issued under the Option Exchange.  These Series A unvested restricted shares of Liberty Interactive and Liberty Ventures had a weighted average grant date fair value of $17.49 and $4.07 per share, respectively.
The aggregate fair value of all restricted shares of Liberty common stock that vested during the years ended December 31, 2014, 2013 and 2012 was $19 million, $16 million and $12 million, respectively.
Other
Certain of the Company's other subsidiaries have stock-based compensation plans under which employees and non-employees are granted options or similar stock-based awards.  Awards made under these plans vest and become exercisable over various terms.  The awards and compensation recorded, if any, under these plans is not significant to Liberty.

Commitments and Contingencies	(17)Commitments and Contingencies
	Operating Leases
	Liberty leases business offices, has entered into satellite transponder lease agreements and uses certain equipment under lease arrangements. Rental expense under such arrangements amounted to $47 million, $50 million and $52 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	A summary of future minimum lease payments under noncancelable operating leases as of December 31, 2014 follows (amounts in millions):
	Years ending December 31:
	2015	$	33
	2016	$	30
	2017	$	28
	2018	$	28
	2019	$	25
	Thereafter	$	126
	It is expected that in the normal course of business, leases that expire generally will be renewed or replaced by leases on other properties; thus, it is anticipated that future lease commitments will not be less than the amount shown for 2014.
	Litigation
	Liberty has contingent liabilities related to legal and tax proceedings and other matters arising in the ordinary course of business. Although it is reasonably possible Liberty may incur losses upon conclusion of such matters, an estimate of any loss or range of loss cannot be made. In the opinion of management, it is expected that amounts, if any, which may be required to satisfy such contingencies will not be material in relation to the accompanying consolidated financial statements.

Information About Liberty's Operating Segments
Information About Liberty's Operating Segments	(18)  Information About Liberty's Operating Segments
	Liberty, through its ownership interests in subsidiaries and other companies, is primarily engaged in the video and on-line commerce industries. Liberty identifies its reportable segments as (A) those consolidated subsidiaries that represent 10% or more of its consolidated annual revenue, annual Adjusted OIBDA or total assets and (B) those equity method affiliates whose share of earnings represent 10% or more of Liberty's annual pre-tax earnings. The segment presentation for prior periods has been conformed to the current period segment presentation.
	Liberty evaluates performance and makes decisions about allocating resources to its operating segments based on financial measures such as revenue, Adjusted OIBDA, gross margin, average sales price per unit, number of units shipped and revenue or sales per customer equivalent. In addition, Liberty reviews nonfinancial measures such as unique website visitors, conversion rates and active customers, as appropriate.
	Liberty defines Adjusted OIBDA as revenue less cost of sales, operating expenses, and selling, general and administrative expenses (excluding stock-based compensation). Liberty believes this measure is an important indicator of the operational strength and performance of its businesses, including each business's ability to service debt and fund capital expenditures. In addition, this measure allows management to view operating results and perform analytical comparisons and benchmarking between businesses and identify strategies to improve performance. This measure of performance excludes depreciation and amortization, stock-based compensation, separately reported litigation settlements and restructuring and impairment charges that are included in the measurement of operating income pursuant to GAAP. Accordingly, Adjusted OIBDA should be considered in addition to, but not as a substitute for, operating income, net income, cash flow provided by operating activities and other measures of financial performance prepared in accordance with GAAP. Liberty generally accounts for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current prices.
	For the year ended December 31, 2014, Liberty has identified the following consolidated subsidiary as its reportable segment:
		·		QVC—consolidated subsidiary that markets and sells a wide variety of consumer products in the United States and several foreign countries, primarily by means of its televised shopping programs and via the Internet and mobile transactions through its domestic and international websites.
	Additionally, for presentation purposes Liberty is providing financial information of the Digital Commerce businesses on an aggregated basis.  The consolidated businesses do not contribute significantly to the overall operations of Liberty on an individual basis; however, Liberty believes that on an aggregated basis they provide relevant information for users of these financial statements.  While these businesses may not meet the aggregation criteria under relevant accounting literature, Liberty believes the information is relevant and helpful for a more complete understanding of the consolidated results.
		·		Digital Commerce—the aggregation of certain consolidated subsidiaries and equity affiliate that market and sell a wide variety of consumer products via the Internet.  Categories of consumer products include perishable and personal gift offerings (Provide, prior to December 31, 2014 and our equity affiliate, FTD, as of December 31, 2014), active lifestyle gear and clothing (Backcountry), fitness and health goods (Bodybuilding), digital invitations (Evite), infant and juvenile-related products (Right Start) and a drop-ship solutions company (CommerceHub).
	Due to the TripAdvisor Holdings Spin-Off completed on August 27, 2014, TripAdvisor is no longer considered a separate reportable segment. Prior to the completion of the TripAdvisor Holdings Spin-Off, BuySeasons was included in the Digital Commerce segment.
	Liberty's operating segments are strategic business units that offer different products and services. They are managed separately because each segment requires different technologies, distribution channels and marketing strategies.  The accounting policies of the segments that are also consolidated subsidiaries are the same as those described in the Company's summary of significant accounting policies.

	Receivables are reflected net of an allowance for doubtful accounts and sales returns.   A provision for bad debts is provided as a percentage of accounts receivable based on historical experience and included in selling, general and administrative expense.  A provision for vendor receivables are determined based on an estimate of probable expected losses and included in cost of goods sold. A summary of activity in the allowance for doubtful accounts is as follows:

	2012		$	80		76		—	-80	76
Inventory	Inventory
	Inventory, consisting primarily of products held for sale, is stated at the lower of cost or market.  Cost is determined by the average cost method, which approximates the first-in, first-out method.  Assessments about the realizability of inventory require the Company to make judgments based on currently available information about the likely method of disposition including sales to individual customers, returns to product vendors, liquidations and the estimated recoverable values of each disposition category.  Inventory is stated net of inventory obsolescence reserves of $86 million and $88 million for the years ended December 31, 2014 and 2013, respectively.
Investments	Investments
	All marketable equity and debt securities held by the Company are classified as available-for-sale ("AFS") and are carried at fair value generally based on quoted market prices.  U.S. generally accepted accounting principles ("GAAP") permit entities to choose to measure many financial instruments, such as AFS securities, and certain other items at fair value and to recognize the changes in fair value of such instruments in the entity's statement of operations (the "fair value option").  Liberty had previously entered into economic hedges for certain of its non-strategic AFS securities (although such instruments were not accounted for as fair value hedges by the Company).  Changes in the fair value of these economic hedges were reflected in Liberty's statement of operations as unrealized gains (losses).  In order to better match the changes in fair value of the subject AFS securities and the changes in fair value of the corresponding economic hedges in the Company's financial statements, Liberty has elected the fair value option for those of its AFS securities which it considers to be non-strategic ("Fair Value Option Securities").  Accordingly, changes in the fair value of Fair Value Option Securities, as determined by quoted market prices, are reported in realized and unrealized gains (losses) on financial instruments in the accompanying consolidated statement of operations.  The total value of AFS securities for which the Company has elected the fair value option aggregated $1,220 million and $1,309 million as of December 31, 2014 and 2013, respectively.
	Other investments in which the Company's ownership interest is less than 20%, unless the Company has the ability to exercise significant influence, and that are not considered marketable securities are carried at cost.
	For those investments in affiliates in which the Company has the ability to exercise significant influence, the equity method of accounting is used.  Under this method, the investment, originally recorded at cost, is adjusted to recognize the Company's share of net earnings or losses of the affiliate as they occur rather than as dividends or other distributions are received.  Losses are limited to the extent of the Company's investment in, advances to and commitments for the investee.  In the event the Company is unable to obtain accurate financial information from an equity affiliate in a timely manner, the Company records its share of earnings or losses of such affiliate on a lag (see note 8).  The Company's share of net earnings or loss of affiliates also includes any other than temporary declines in fair value recognized during the period.
	Changes in the Company's proportionate share of the underlying equity of an equity method investee, which result from the issuance of additional equity securities by such equity investee, are recognized in the statement of operations through the other, net line item.  To the extent there is a difference between our ownership percentage in the underlying equity of an equity method investee and our carrying value, such difference is accounted for as if the equity method investee were a consolidated subsidiary.
	The Company continually reviews its equity investments and its AFS securities which are not Fair Value Option Securities to determine whether a decline in fair value below the carrying value is other than temporary.  The primary factors the Company considers in its determination are the length of time that the fair value of the investment is below the Company's carrying value; the severity of the decline; and the financial condition, operating performance and near term prospects of the investee.  In addition, the Company considers the reason for the decline in fair value, be it general market conditions, industry specific or investee specific; analysts' ratings and estimates of 12 month share price targets for the investee; changes in stock price or valuation subsequent to the balance sheet date; and the Company's intent and ability to hold the investment for a period of time sufficient to allow for a recovery in fair value.  If the decline in fair value is deemed to be other than temporary, the carrying value of the security is written down to fair value.  In situations where the fair value of an investment is not evident due to a lack of a public market price or other factors, the Company uses its best estimates and assumptions to arrive at the estimated fair value of such investment.  The Company's assessment of the foregoing factors involves considerable management judgment and accordingly, actual results may differ materially from the Company's estimates and judgments.  Writedowns for AFS securities which are not Fair Value Option Securities would be included in the consolidated statements of operations as other than temporary declines in fair values of investments.  Writedowns for equity method investments would be included in share of earnings (losses) of affiliates.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	All of the Company's derivatives, whether designated in hedging relationships or not, are recorded on the balance sheet at fair value.  If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings.  If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive earnings and are recognized in the statement of operations when the hedged item affects earnings.  Ineffective portions of changes in the fair value of cash flow hedges are recognized in earnings.  If the derivative is not designated as a hedge, changes in the fair value of the derivative are recognized in earnings.  The Company has entered into several interest rate swap agreements to mitigate the cash flow risk associated with interest payments related to certain of its variable rate debt.  None of the Company's derivatives are currently designated as hedges.
	The fair value of the Company's derivative instruments are estimated using the Black-Scholes model.  The Black-Scholes model incorporates a number of variables in determining such fair values, including expected volatility of the underlying security and an appropriate discount rate.  The Company obtains volatility rates from pricing services based on the expected volatility of the underlying security over the remaining term of the derivative instrument.  A discount rate is obtained at the inception of the derivative instrument and updated each reporting period in which equity collars are outstanding, based on the Company's estimate of the discount rate at which it could currently settle the derivative instrument.  The Company considered its own credit risk as well as the credit risk of its counterparties in estimating the discount rate.  Management judgment was required in estimating the Black-Scholes variables.
Property and Equipment
	Property and Equipment
	Property and equipment consisted of the following:
			December 31,			December 31,
			2014			2013
			amounts in millions
	Land		$	205		208
	Buildings and improvements			935		976
	Support equipment			847		940
	Projects in progress			43		77
	Total property and equipment		$	2,030		2,201
	Property and equipment, including significant improvements, is stated at cost. Depreciation is computed using the straight-line method using estimated useful lives of 2 to 15 years for support equipment and 8 to 20 years for buildings and improvements.  Depreciation expense for the years ended December 31, 2014, 2013 and 2012 was $158 million, $147 million and $142 million, respectively.
Intangible Assets	Intangible Assets
	Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment upon certain triggering events.  Goodwill and other intangible assets with indefinite useful lives (collectively, "indefinite lived intangible assets") are not amortized, but instead are tested for impairment at least annually.  Our annual impairment assessment of our indefinite-lived intangible assets is performed during the fourth quarter of each year.
	The Company utilizes a qualitative assessment for determining whether step one of the goodwill impairment analysis is necessary.  The accounting guidance permits entities to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test.  In evaluating goodwill on a qualitative basis the Company reviews the business performance of each reporting unit and evaluates other relevant factors as identified in the relevant accounting guidance to determine whether it was more likely than not that an indicated impairment exists for any of our reporting units. The Company considers whether there are any negative macroeconomic conditions, industry specific conditions, market changes, increased competition, increased costs in doing business, management challenges, the legal environments and how these factors might impact company specific performance in future periods. As part of the analysis the Company also considers fair value determinations for certain reporting units that have been made at various points throughout the current year and prior year for other purposes.
	If a step one test is considered necessary based on the qualitative factors, the Company compares the estimated fair value of a reporting unit to its carrying value. Developing estimates of fair value requires significant judgments, including making assumptions about appropriate discount rates, perpetual growth rates, relevant comparable market multiples, public trading prices and the amount and timing of expected future cash flows. The cash flows employed in Liberty's valuation analyses are based on management's best estimates considering current marketplace factors and risks as well as assumptions of growth rates in future years. There is no assurance that actual results in the future will approximate these forecasts. For those reporting units whose carrying value exceeds the fair value, a second test is required to measure the impairment loss (the "Step 2 Test"). In the Step 2 Test, the fair value (Level 3) of the reporting unit is allocated to all of the assets and liabilities of the reporting unit with any residual value being allocated to goodwill. Any excess of the carrying value of the goodwill over this allocated amount is recorded as an impairment charge.
Impairment of Long-lived Assets	Impairment of Long-lived Assets
	The Company periodically reviews the carrying amounts of its property and equipment and its intangible assets (other than goodwill and indefinite-lived intangibles) to determine whether current events or circumstances indicate that such carrying amounts may not be recoverable.  If the carrying amount of the asset group is greater than the expected undiscounted cash flows to be generated by such asset group, including its ultimate disposition, an impairment adjustment is to be recognized.  Such adjustment is measured by the amount that the carrying value of such asset groups exceeds their fair value.  The Company generally measures fair value by considering sale prices for similar asset groups or by discounting estimated future cash flows using an appropriate discount rate.  Considerable management judgment is necessary to estimate the fair value of asset groups.  Accordingly, actual results could vary significantly from such estimates.  Asset groups to be disposed of are carried at the lower of their financial statement carrying amount or fair value less costs to sell.
Noncontrolling Interests	Noncontrolling Interests
	The Company reports noncontrolling interests of subsidiaries within equity in the balance sheet and the amount of consolidated net income attributable to the parent and to the noncontrolling interest is presented in the statement of operations.  Also, changes in ownership interests in subsidiaries in which the Company maintains a controlling interest are recorded in equity.
Foreign Currency Translation	Foreign Currency Translation
	The functional currency of the Company is the United States (''U.S.'') dollar.  The functional currency of the Company's foreign operations generally is the applicable local currency for each foreign subsidiary.  Assets and liabilities of foreign subsidiaries are translated at the spot rate in effect at the applicable reporting date, and the 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 in stockholders' equity.
	Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise.  Subsequent changes in exchange rates result in transaction gains and losses which are reflected in the accompanying consolidated statements of operations and comprehensive earnings (loss) as unrealized (based on the applicable period-end exchange rate) or realized upon settlement of the transactions.
Revenue Recognition	Revenue Recognition
	Retail revenue is recognized at the time of delivery to customers.  The revenue for shipments in-transit is recorded as deferred revenue and included in other current liabilities.  Service revenue is recognized when the applicable criteria are met: persuasive evidence of an arrangement exists, services have been rendered, the price is fixed and determinable and collectability is reasonably assured.
	An allowance for returned merchandise is provided as a percentage of sales based on historical experience.  The total reduction in sales due to returns for the years ended December 31, 2014, 2013 and 2012 aggregated $2,123 million, $2,134 million and $2,037 million, respectively.  Sales tax collected from customers on retail sales is recorded on a net basis and is not included in revenue.
	In May 2014, the Financial Accounting Standards Board issued new accounting guidance on revenue from contracts with customers. The new guidance 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. The updated guidance will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either a retrospective or cumulative effect transition method. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its revenue recognition but does not believe that the standard will significantly impact its financial statements and related disclosures.
Cost of Sales	Cost of Sales
	Cost of sales primarily includes actual product cost, provision for obsolete inventory, buying allowances received from suppliers, shipping and handling costs and warehouse costs.
Advertising Costs	Advertising Costs
	Advertising costs generally are expensed as incurred.  Advertising expense aggregated $271 million, $258 million and $247 million for the years ended December 31, 2014, 2013 and 2012, respectively. Advertising costs are reflected in the Selling, general and administrative expense line item in our consolidated statements of operations.
Stock-Based Compensation	Stock-Based Compensation
	As more fully described in note 14, the Company has granted to its directors, employees and employees of its subsidiaries options, restricted stock and stock appreciation rights ("SARs") to purchase shares of Liberty Interactive and/or Liberty Ventures common stock ("Liberty common stock") (collectively, "Awards").  The Company measures the cost of employee services received in exchange for an Award of equity instruments (such as stock options and restricted stock) based on the grant-date fair value of the Award, and recognizes that cost over the period during which the employee is required to provide service (usually the vesting period of the Award).  The Company measures the cost of employee services received in exchange for an Award of liability instruments (such as stock appreciation rights that will be settled in cash) based on the current fair value of the Award, and remeasures the fair value of the Award at each reporting date.
	Stock compensation expense was $108 million, $118 million and $91 million for the years ended December 31, 2014, 2013 and 2012, respectively, included in selling, general and administrative expense in the accompanying consolidated statements of operations.
Income Taxes	Income Taxes
	The Company accounts for income taxes using the asset and liability method.  Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying value amounts and income tax bases of assets and liabilities and the expected benefits of utilizing net operating loss and tax credit carryforwards.  The deferred tax assets and liabilities are calculated using enacted tax rates in effect for each taxing jurisdiction in which the Company operates for the year in which those temporary differences are expected to be recovered or settled.  Net deferred tax assets are then reduced by a valuation allowance if the Company believes it more likely than not such net deferred tax assets will not be realized.  The effect on deferred tax assets and liabilities of an enacted change in tax rates is recognized in income in the period that includes the enactment date.
	When the tax law requires interest to be paid on an underpayment of income taxes, the Company recognizes interest expense from the first period the interest would begin accruing according to the relevant tax law.  Such interest expense is included in interest expense in the accompanying consolidated statements of operations.  Any accrual of penalties related to underpayment of income taxes on uncertain tax positions is included in other income (expense) in the accompanying consolidated statements of operations.
Earnings (Loss) Attributable to Liberty Interactive Corporation Stockholders and Earnings (Loss) Per Common Share	Earnings (Loss) Attributable to Liberty Interactive Corporation Stockholders and Earnings (Loss) Per Common Share
	Net earnings (loss) attributable to Liberty stockholders is comprised of the following (amounts in millions):

	Liberty Interactive Corporation
	Net earnings (loss) from continuing operations		NA		NA		-1

	Net earnings (loss) from continuing operations	$	3		54		281
	Net earnings (loss) from discontinued operations	$	14		9		743
	Basic earnings (loss) per common share ("EPS") is computed by dividing net earnings (loss) attributable to such common stock by the weighted average number of common shares outstanding for the period. Diluted EPS presents the dilutive effect on a per share basis of potential common shares as if they had been converted at the beginning of the periods presented.
	Series A and Series B Liberty Interactive Corporation Common Stock
	The basic and diluted EPS calculation for Liberty Interactive Corporation prior to the recapitalization is based on the following weighted average outstanding shares. Excluded from diluted EPS, for the period prior to the recapitalization, are less than a million potential common shares because their inclusion would be antidilutive.

	Liberty completed a recapitalization on August 9, 2012, whereby each holder of current Liberty Interactive Corporation common stock became a holder of the same number of Liberty Interactive common stock. EPS for the period from the recapitalization through December 31, 2014, is based on the following weighted average outstanding shares.  Excluded from diluted EPS for the year ended December 31, 2014 are approximately 1 million potential common shares because their inclusion would be antidilutive.

	Series A and Series B Liberty Ventures Common Stock
	Liberty completed a recapitalization on August 9, 2012, whereby each holder of then-existing Liberty Interactive common stock received 0.05 of a share of the corresponding series of Liberty Ventures common stock, by means of a dividend, with cash paid in lieu of fractional shares of Liberty Ventures common stock.  Additionally, as part of the recapitalization Liberty distributed subscription rights, which were priced at a discount to the market value, to all holders of Liberty Ventures common stock, see further discussion in note 12.  The rights offering, because of the discount, is considered a stock dividend which requires retroactive treatment for prior periods for the weighted average shares outstanding. As discussed in note 2, Liberty completed a two for one stock split on April 11, 2014 on its Series A and Series B Liberty Ventures common stock.  Therefore, all prior period outstanding share amounts have been retroactively adjusted for comparability.
	Additionally, as discussed in note 2, on October 3, 2014, Liberty attributed from the QVC Group to the Ventures Group its Digital Commerce companies. In exchange for the Reattributed Assets, Inter-Group Interest Shares in the Ventures Group were created in favor of the QVC Group. Immediately following the reattribution on October 3, 2014, Liberty's board declared a dividend of the Inter-Group Interest Shares to the holders of Series A and Series B Liberty Interactive common stock in full elimination of the inter-group interest. The Inter-Group Interest Shares were allocated, pro-rata, to the outstanding shares of Series A and Series B Liberty Interactive common stock at 5:00 p.m., New York City time, on October 13, 2014, the record date for the dividend, such that each holder of Liberty Interactive common stock received 0.14217 of a share of the corresponding series of Liberty Ventures common stock for each share of Liberty Interactive common stock held as of the record date, with cash paid in lieu of fractional shares. The distribution date for the dividend was on October 20, 2014, and the Liberty Interactive common stock began trading ex-dividend on October 15, 2014. The reattribution of the Digital Commerce companies is presented on a prospective basis from the date of the reattribution in Liberty’s consolidated financial statements, with October 1, 2014 used as a proxy for the date of the reattribution.
	EPS for the period from the recapitalization through December 31, 2014, is based on the following weighted average outstanding shares.  Excluded from diluted EPS for the year ended December 31, 2014 are less than a million potential common shares because their inclusion would be antidilutive.

Estimates	Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.  Actual results could differ from those estimates.  Liberty considers (i) recurring and non-recurring fair value measurements, (ii) accounting for income taxes, (iii) assessments of other-than-temporary declines in fair value of its investments and (iv) estimates of retail-related adjustments and allowances to be its most significant estimates.
	Liberty holds investments that are accounted for using the equity method.  Liberty does not control the decision making process or business management practices of these affiliates.  Accordingly, Liberty relies on management of these affiliates to provide it with accurate financial information prepared in accordance with GAAP that Liberty uses in the application of the equity method.  In addition, Liberty relies on audit reports that are provided by the affiliates' independent auditors on the financial statements of such affiliates.  The Company is not aware, however, of any errors in or possible misstatements of the financial information provided by its equity affiliates that would have a material effect on Liberty's consolidated financial statements.

		-1		Liberty entered into a forward sales contract on 12 million shares of Expedia common stock in March 2012 at a per share forward price of $34.316.  The forward contract was settled in October 2012 for total cash proceeds of $412 million and the 12 million shares of Expedia common stock, previously held as collateral, were released to the counterparty.  In the fourth quarter of 2012, when the forward contract settled, the difference between the fair value of the Expedia shares and the carrying value of the shares ($443 million) was recognized in the gain (loss) on transactions, net line item in the statement of operations. Liberty owns an approximate 18% equity interest and 58% voting interest in Expedia.  Liberty has entered into governance arrangements pursuant to which Mr. Barry Diller, Chairman of the Board and Senior Executive Officer of Expedia, may vote its interests of Expedia, subject to certain limitations.  Additionally, through our governance arrangements with Mr. Diller, we have the right to appoint and have appointed 20% of the members of Expedia's board of directors, which is currently comprised of 10 members.  Therefore, we determined based on these arrangements that we have significant influence and have accounted for the investment as an equity method affiliate.
		-2		During the years ended December 31, 2014, 2013 and 2012, Expedia, Inc. paid dividends aggregating $15 million, $13 million and $23 million, respectively, and HSN, Inc. paid dividends of $22 million and $16 million during the years ended December 31, 2014 and December 31, 2013, respectively, which were recorded as reductions to the investment balances.
		-3		As discussed in note 1, FTD acquired Liberty’s formerly wholly-owned subsidiary, Provide, on December 31, 2014. In exchange for Provide, Liberty received approximately 10.2 million shares of FTD common stock representing approximately 35% of the combined company and approximately $145 million in cash. Subsequent to completion of the transaction, Liberty accounts for FTD as an equity-method affiliate based on the ownership level and board representation.
