Basis of Presentation [Abstract]	'
Business Description and Basis of Presentation [Text Block]	'
	Basis of Presentation
	The accompanying condensed consolidated financial statements include the accounts of Liberty Interactive 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.
	The accompanying (a) condensed consolidated balance sheet as of December 31, 2012, which has been derived from audited financial statements, and (b) the interim unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for such periods have been included. Certain amounts included in the accompanying financial statements for 2012 have been reclassified and adjusted to conform to the 2013 financial statement presentation. During the current period, due to the increased level of activity, we changed the presentation of Net sales (purchases) of short term investments and other marketable securities to present gross amounts in the consolidated statement of cash flows, in order to conform to GAAP requirements. The results of operations for any interim period are not necessarily indicative of results for the full year. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in Liberty's Annual Report on Form 10-K for the year ended December 31, 2012.
	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) fair value measurement, (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 condensed consolidated financial statements.
	In September 2011, Liberty completed the split-off (the “Split-Off”) of its former wholly-owned subsidiary (then named Liberty Media Corporation), which at the time of the Split-Off held all of the businesses, assets and liabilities attributed to Liberty's then Capital and Starz tracking stock groups. In January 2013, this entity (now named Starz) spun-off (the “Spin-Off”) its former wholly-owned subsidiary, Liberty Media Corporation ("LMC"). Following the Split-Off and Spin-Off, Liberty, LMC and Starz each operate as separate publicly traded companies, none of which has any stock ownership, beneficial or otherwise, in the other.

	In connection with the Split-Off, Liberty entered a Reorganization Agreement, a Services Agreement, a Facilities Sharing Agreement and a Tax Sharing Agreement with the split-off entity (now known as Starz). All of these agreements, with the exception of the Tax Sharing Agreement, were assigned by Starz to LMC in connection with the Spin-Off. The Reorganization Agreement provides for, among other things, provisions governing the relationship between Liberty and LMC following the Split-Off, including certain cross-indemnities. Pursuant to the Services Agreement, LMC provides Liberty with certain general and administrative services including legal, tax, accounting, treasury and investor relations support. Liberty reimburses 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, LMC shares office space and related amenities at its corporate headquarters with Liberty. Under these various agreements, approximately $4 million and $12 million of allocated expenses were reimbursable by Liberty to LMC for the three and nine months ended September 30, 2013, respectively, and approximately $4 million and $9 million for the three and nine months ended September 30, 2012, respectively. The Tax Sharing Agreement provides for the allocation and indemnification of tax liabilities and benefits between Liberty and Starz and other agreements related to tax matters. With respect to the Split-Off, the IRS has examined the transaction, and during 2012, the IRS and Liberty Interactive entered into a Closing Agreement which provides that the Split-Off qualified for tax-free treatment to Liberty and Starz. In April 2013, the IRS completed its review of the Spin-Off and notified the parties that it agreed with the nontaxable characterization of the transaction.

	On December 11, 2012, we acquired approximately 4.8 million additional shares of common stock of TripAdvisor, Inc. ("TripAdvisor") (an additional 4% equity ownership interest), for $300 million, along with the right to control the vote of the shares of TripAdvisor's common stock and class B common stock we own. Following the transaction, we own approximately 22% of the equity and 57% of the total votes of all classes of TripAdvisor common stock. As this transaction resulted in Liberty gaining control of TripAdvisor, we applied the applicable purchase accounting guidance. The fair value of our ownership interest previously held and the fair value of the noncontrolling interest (Level 1) was determined based on the trading price of TripAdvisor common shares on the last trading day prior to our transaction. Additionally, the noncontrolling interest includes the fair value of TripAdvisor's fully vested options (Level 2) outstanding at the date of acquisition. Following the transaction date, TripAdvisor is a consolidated subsidiary with a 78% noncontrolling interest accounted for in equity and the condensed consolidated statements of operations. Other than a $30 million re-classification from the "Intangibles subject to amortization" line item to the "Trademarks" line item, there have been no significant changes to our purchase price allocation since December 31, 2012.

	Liberty announced that its board has authorized management to pursue a plan to recapitalize (the "Recapitalization") its Liberty Interactive Group tracking stock into two new tracking stocks, one (currently the Liberty Interactive common stock) to be renamed the QVC Group common stock and the other to be designated as the Liberty Digital Commerce common stock. In the Recapitalization, record holders of Series A and Series B Liberty Interactive common stock would receive 1 share of the corresponding series of Liberty Digital Commerce common stock for each 10 shares of the renamed QVC Group common stock held by them as of the effective date. Liberty intends to attribute to the Liberty Digital Commerce Group its operating subsidiaries Provide Commerce, Inc., Backcountry.com, Inc., Bodybuilding.com, LLC, CommerceHub, Right Start and Evite along with cash and certain liabilities. The QVC Group, which is currently known as the Liberty Interactive Group, would have attributed to it Liberty's subsidiary QVC, Inc. and an approximate 38% interest in HSN, Inc. ("HSNi"), along with cash and certain liabilities.

	Additionally, Liberty announced that its board has also authorized management to pursue a plan to spin-off to holders of its Liberty Ventures Group tracking stock shares of a newly formed company (the “Trip spin-off”) to be called Liberty TripAdvisor Holdings ("Trip Holdings"). Trip Holdings would be comprised of, among other things, Liberty's 22% economic and 57% voting interest in TripAdvisor, as well as Liberty's BuySeasons business, which is currently a part of Liberty's subsidiary Celebrate Interactive, LLC ("Celebrate Interactive"). BuySeasons would be reattributed from the Liberty Interactive Group to the Liberty Ventures Group prior to the Trip spin-off (or, if following the Recapitalization, from the new Liberty Digital Commerce Group to the Liberty Ventures Group) and cash equal to the fair market value of BuySeasons would be reattributed from the Liberty Ventures Group to the Liberty Interactive Group. The Evite business, also currently a part of Celebrate Interactive, would remain at Liberty attributed to the Liberty Interactive Group (or, assuming the completion of the Recapitalization, the new Liberty Digital Commerce Group). In the Trip spin-off, record holders of Series A and Series B Liberty Ventures common stock would receive 1 share of the corresponding series of Trip Holdings common stock for each share of the Liberty Ventures common stock held by them as of a to-be-determined record date.

	The Recapitalization and the Trip spin-off will be subject to various conditions. The Recapitalization is subject to the requisite approval of the holders of Liberty Interactive common stock and Liberty Ventures common stock at a stockholders' meeting and the receipt of the opinion of tax counsel. The Trip spin-off is intended to be tax-free to stockholders of Liberty and its completion is conditioned upon the receipt of an IRS private letter ruling and an opinion of tax counsel. Subject to the satisfaction of these conditions and final board consideration and approval, the Recapitalization and Trip spin-off are expected to occur in the first half of 2014. However, neither the Recapitalization nor the Trip spin-off is conditioned on the other, and no assurance can be given as to which transaction will occur first, if at all.

	Tracking Stocks

	On August 9, 2012, Liberty completed the approved recapitalization (the "2012 recapitalization") of its common stock through the creation of the Liberty Interactive common stock and Liberty Ventures common stock as tracking stocks. In the 2012 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.
	A 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 Interactive Group and Ventures Group, respectively. While the Interactive 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 stocks 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. The Ventures Group is primarily comprised of TripAdvisor, a consolidated subsidiary, and interests in Expedia, Inc., Interval Leisure Group, Inc., Tree.com, Inc., investments in Time Warner Inc. and Time Warner Cable Inc., as well as cash in the amount of approximately $526 million (at September 30, 2013). The Ventures Group also has attributed to it certain liabilities related to our corporate indebtedness (see note 9) 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 "Interactive Group" does not represent a separate legal entity, rather it represents those businesses, assets and liabilities that have been attributed to that group. The Interactive Group is primarily focused on video and e-commerce operating businesses and has attributed to it the remainder of Liberty's businesses and assets, including operating subsidiaries QVC, Inc. ("QVC"), Provide Commerce, Inc., Backcountry.com, Inc., Bodybuilding.com, LLC, Celebrate Interactive Holdings, LLC and CommerceHub as well as interests in HSN, Inc., and cash of approximately $455 million (at September 30, 2013), which includes subsidiary cash. The Interactive Group has attributed to it liabilities that reside with QVC and the other entities listed as well certain liabilities related to our corporate indebtedness (see note 9) and certain deferred tax liabilities.
	See Exhibit 99.1 to this Quarterly Report on Form 10-Q for unaudited attributed financial information for Liberty's tracking stock groups.

Share-based Compensation [Abstract]	'
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company has granted to certain of its directors, employees and employees of its subsidiaries stock appreciation rights ("SARs"), restricted stock grants and options to purchase shares of Liberty common stock (collectively, "Awards"). The Company measures the cost of employee services received in exchange for an equity classified Award (such as stock options and restricted stock grants) 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 a liability classified Award (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.
	Included in the accompanying condensed consolidated statements of operations are the following amounts of stock-based compensation, a portion of which relates to TripAdvisor as discussed below:


		Three months ended						Nine months ended
		September 30,						September 30,

	Selling, general and administrative expense	31				18		104				53

		$	38			18		124				53

	During the nine months ended September 30, 2013, Liberty granted, primarily to QVC employees, 4.2 million options to purchase shares of Series A Liberty Interactive common stock. Such options had a weighted average grant-date fair value of $8.16 per share and vest semi-annually over the 4 year vesting period.
	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. The volatility used in the calculation for Awards is based on the historical volatility of Liberty's stock 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 tables present 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 of September 30, 2013, the total unrecognized compensation cost related to unvested Liberty outstanding equity Awards was approximately $125 million, including compensation associated with the option exchange that occured in December 2012. Such amount will be recognized in the Company's consolidated statements of operations over a weighted average period of approximately 2.3 years.
TripAdvisor - Stock-based Compensation
During the nine months ended September 30, 2013, TripAdvisor issued 2.8 million of primarily service based stock options under their 2011 Incentive Plan with a weighted average estimated grant-date fair value per option of $28.11. As of September 30, 2013, TripAdvisor has 9.7 million options outstanding of which 3.5 million are exercisable. TripAdvisor stock-based compensation for the three and nine months ended September 30, 2013 was approximately $14 million and $44 million, respectively. As of September 30, 2013, the total unrecognized compensation cost related to unvested TripAdvisor stock options was approximately $112 million and will be recognized over a weighted average period of approximately 3.5 years.
Additionally, during the nine months ended September 30, 2013, TripAdvisor granted 1.1 million service based RSUs under their 2011 Incentive Plan for which the fair value was measured based on the quoted price of TripAdvisor common stock at the date of grant. As of September 30, 2013, the total unrecognized compensation cost related to 1.1 million unvested TripAdvisor RSUs was approximately $39 million and will be recognized over a weighted average period of approximately 3.3 years.
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.

	Earnings (Loss) Per Common Share
	Basic earnings (loss) per common share ("EPS") is computed by dividing net earnings (loss) 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 number of weighted average shares outstanding. Excluded from diluted EPS, for the three and nine months ended September 30, 2012, prior to the 2012 recapitalization, are 7 million potential common shares because their inclusion would be antidilutive. As discussed in more detail in note 2, Liberty Interactive Corporation common stock was recapitalized through the creation of the Liberty Interactive common stock and Liberty Ventures common stock as tracking stocks during the third quarter of 2012. Therefore, there is no Liberty Interactive Corporation common stock outstanding at September 30, 2013.

Assets And Liabilities Measured At Fair Value	'
	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 are inputs, other than quoted market prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.






	The Company's assets and liabilities measured at fair value are as follows:


					Fair Value Measurements at September 30, 2013
	Description	Total			Quoted prices		Significant other		Significant
					in active markets		observable		unobservable
					for identical assets		inputs		inputs

	Debt	$	2,236		—		2,236		—

	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.
	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
	All marketable equity and debt securities held by the Company are classified as available-for-sale ("AFS") and are carried at fair value 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 statements 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 considered 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 condensed 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's 22% owned consolidated subsidiary TripAdvisor, Inc. earned revenue of approximately $56 million and $171 million for the three and nine months ended September 30, 2013, respectively, and $57 million and $164 million for the three and nine months ended September 30, 2012, respectively, from Expedia, Inc. (TripAdvisor's former parent).

	-2	Liberty invested $300 million in a solar energy plant on September 30, 2013. Liberty expects to receive a portion of the initial investment back within a year as the entity expects to receive grant proceeds and other favorable tax attributes once the solar plant is operational. Similar to some of Liberty's other alternative energy investments, the Company expects to record the Company's share of losses of the solar plant initially but expects to record the impacts of favorable tax attributes (primarily accelerated depreciation) as a current tax benefit with an offsetting deferred tax expense in the tax expense (benefit) line item in the Statement of Operations.

	QVC Bank Credit Facilities
	On March 1, 2013, QVC entered into an amended and restated syndicated senior secured credit agreement which served to refinance QVC's existing bank credit facility (the “Amended and Restated Credit Agreement”). The Amended and Restated Credit Agreement 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 covenants contained in the Amended and Restated Credit Agreement are substantially similar to those contained in QVC's previously existing bank credit facility. Borrowings under the Amended and Restated Credit Agreement 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. 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 Amended and Restated Credit Agreement is secured by the stock of QVC. Availability under the QVC Amended and Restated Credit Agreement at September 30, 2013 was $1,327 million. QVC was in compliance with all debt covenants related to the Amended and Restated Credit Agreement at September 30, 2013.
	QVC Senior Secured Notes
	On March 4, 2013, QVC announced the commencement of cash tender offers (the “Offers”) for any and all of its outstanding $500 million in aggregate principal amount of 7.125% senior secured notes due 2017 (the “7.125% Senior Notes”) and up to $250 million in aggregate principal amount of its 7.5% senior secured notes due 2019 (the “7.5% Senior Notes”). The Offer for the 7.125% Senior Notes expired on March 15, 2013, and the Offer for the 7.5% Senior Notes expired on April 1, 2013. Approximately $124 million of the 7.125% Senior Notes were tendered pursuant to the Offers, whereby holders of the 7.125% Senior Notes received consideration of $1,039.40 for each $1,000 principal amount of tendered 7.125% Senior Notes purchased pursuant to the Offers. QVC called the remaining $376 million principal of its 7.125% Senior Notes at $1,035.63 for each $1,000 principal amount of 7.125% Senior Notes on April 17, 2013. Approximately $231 million of the 7.5% Senior Notes were tendered pursuant to the Offers. The total consideration for the 7.5% Senior Notes was $1,120 for each $1,000 principal amount of tendered 7.5% Senior Notes.
	On March 18, 2013, QVC completed the offering of $750 million principal amount of new 4.375% senior secured notes due 2023 and $300 million principal amount of new 5.95% senior secured notes due 2043 (collectively, the “Notes”). The Notes are secured by a first-priority lien on QVC's capital stock, pari passu with the Amended and Restated Credit Agreement and QVC's existing notes. The net proceeds from the offering of the Notes were used to fund the Offers, repay outstanding amounts on QVC's existing bank credit facility and, via dividend from QVC, retire Liberty's 5.7% Senior Notes due May 2013, and for general corporate purposes.
As a result of these refinancing transactions, QVC recorded extinguishment losses of $57 million for the nine months ended September 30, 2013, which is recorded in other, net in the Company's statements of operations.
QVC was in compliance with all of its debt covenants related to its outstanding senior notes at September 30, 2013.
QVC Interest Rate Swap Arrangements
In March 2013, QVC's notional interest rate swaps of $3.1 billion expired. 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 condensed consolidated statements of operations.
Interactive Exchangeable Senior Debentures
On September 9, 2013, Liberty LLC, a wholly owned subsidiary of Liberty, issued $400 million aggregate original principal amount of the 1% Exchangeable Senior Debentures due 2043 (the "HSNi Exchangeables"). The HSNi Exchangeables mature on September 30, 2043 and interest on the HSNi Exchangeables accrues at an annual rate of 1% of the original principal amount of $1,000 per debenture, payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, commencing December 31, 2013. Each $1,000 original principal amount of 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 after the calendar quarter ending 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.
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.
Due to the restrictions on the delivery of HSNi shares and exchangeability of the debentures at the option of the holder beyond March 31, 2014, Liberty has classified the HSNi Exchangeables as a current liability in the Balance Sheet. Liberty has elected to account for the HSNi 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.
Ventures Exchangeable Senior Debentures
During the nine months ended September 30, 2013, Liberty retired all outstanding 3.25% Exchangeable Senior Debentures due 2031. Liberty paid approximately $414 million to retire the outstanding principal balance.
On April 9, 2013, Liberty's wholly owned subsidiary, Liberty Interactive LLC, called for the redemption of all the outstanding 3.125% Exchangeable Senior Debentures due 2023 ("3.125% Exchangeable Senior Debentures") on May 9, 2013 (the "redemption date"). In accordance with the redemption provisions of the 3.125% Exchangeable Senior Debentures and the related indenture, the 3.125% Exchangeable Senior Debentures were redeemed at a redemption price of approximately $1,667 for each $1,000 principal amount outstanding, which was equal to the sum of (i) the adjusted principal amount of such debenture in effect on the redemption date, (ii) any accrued and unpaid interest on such debenture to the redemption date and (iii) subject to certain conditions, any final period distribution on such debenture. Interest on the debentures ceased accruing on and after the redemption date. Liberty had the option to satisfy the value of the exchange in cash, Time Warner Inc., Time Warner Cable Inc. and AOL, Inc. common stock, or a combination thereof. All of the outstanding 3.125% Exchangeable Senior Debentures were redeemed prior to June 30, 2013, using cash provided by the Debentures (defined below) and cash provided by the sale of shares of Time Warner Inc. and AOL, Inc. common stock.
Also on April 9, 2013, Liberty Interactive LLC, a wholly owned subsidiary Liberty, completed the offer and sale of $850 million aggregate original principal amount of Liberty Interactive LLC's 0.75% Exchangeable Senior Debentures due 2043 (the “Debentures”) in a private placement transaction. The Debentures mature on March 30, 2043. Interest on the Debentures will accrue from April 9, 2013 at an annual rate of 0.75% of the original principal amount of $1,000 per Debenture, payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year, commencing June 30, 2013. Each $1,000 original principal amount of Debentures is initially exchangeable for a basket of 6.3040 shares of common stock of Time Warner Cable Inc. and 5.1635 shares of common stock of Time Warner 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, 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. Liberty has elected to account for this instrument 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.
Other Subsidiary Debt
Other subsidiary debt at September 30, 2013 is comprised of capitalized satellite transponder lease obligations and bank debt of certain subsidiaries.
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 (Level 2). The fair value of Liberty's publicly traded debt securities that are not reported at fair value in the accompanying condensed consolidated balance sheet at September 30, 2013 are as follows (amounts in millions):


Senior debentures	$	837

QVC senior secured notes	$	2,828

Due to the variable rate nature, Liberty believes that the carrying amount of its other debt, not discussed above, approximated fair value at September 30, 2013.

	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 all 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 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 nine months ended September 30, 2013, Liberty has identified the following consolidated subsidiaries as its reportable segments:

	•	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 through its domestic and international websites and mobile applications.

	•	TripAdvisor, Inc. - a consolidated subsidiary that is an online travel research company that empowers users to plan and maximize their travel experience.
	Additionally, for presentation purposes, Liberty is providing financial information of the E-commerce businesses on an aggregated basis. The consolidated E-commerce 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.

	•	E-commerce - the aggregation of certain consolidated subsidiaries that market and sell a wide variety of consumer products via the Internet. Categories of consumer products include perishable and personal gift offerings (Provide Commerce, Inc.), active lifestyle gear and clothing (Backcountry.com, Inc.), fitness and health goods (Bodybuilding.com, LLC), celebration offerings from invitations to costumes (Celebrate Interactive Holdings LLC) and a drop-ship solutions company (CommerceHub).
	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 in the Annual Report on Form 10-K for the year ended December 31, 2012.

In the first quarter of 2012, we entered into a forward contract to sell 12 million Expedia, Inc. shares at approximately $34 per share. The derivative contract was in a liability position in the prior year as the stock price of Expedia, Inc. shares had increased since the inception of the derivative contract and resulted in a recognition of unrealized losses on the contract in the prior year. The contract was settled during the fourth quarter of 2012.

[1]	Liberty's 22% owned consolidated subsidiary TripAdvisor, Inc. earned revenue of approximately $56 million and $171 million for the three and nine months ended September 30, 2013, respectively, and $57 million and $164 million for the three and nine months ended September 30, 2012, respectively, from Expedia, Inc. (TripAdvisor's former parent).
[2]	Liberty invested $300 million in a solar energy plant on September 30, 2013. Liberty expects to receive a portion of the initial investment back within a year as the entity expects to receive grant proceeds and other favorable tax attributes once the solar plant is operational. Similar to some of Liberty's other alternative energy investments, the Company expects to record the Company's share of losses of the solar plant initially but expects to record the impacts of favorable tax attributes (primarily accelerated depreciation) as a current tax benefit with an offsetting deferred tax expense in the tax expense (benefit) line item in the Statement of Operations.
