Notes to Attributed Financial Information

(unaudited)

(1): The assets attributed to our Interactive Group include our consolidated subsidiaries QVC, Inc., Provide Commerce, Inc., Backcountry.com, Inc., Bodybuilding.com, LLC and Celebrate Interactive Holdings, Inc., and our interests in GSI Commerce, Inc., Expedia, Inc., HSN, Inc., Interval Leisure Group, Inc. and Tree.com, Inc. Accordingly, the accompanying attributed financial information for the Interactive Group includes our investments in Expedia, HSN, Interval and Lending Tree, as well as the assets, liabilities, revenue, expenses and cash flows of QVC, Provide, Backcountry, Bodybuilding and Celebrate. We have also attributed certain of our debt obligations (and related interest expense) to the Interactive Group based upon a number of factors, including the cash flow available to the Interactive Group and its ability to pay debt service and our assessment of the optimal capitalization for the Interactive Group. The specific debt obligations attributed to each of the Interactive Group, the Starz Group and the Capital Group are described in note 4 below. In addition, we have allocated certain corporate general and administrative expenses among the Interactive Group, the Starz Group and the Capital Group as described in note 5 below.

The Interactive Group focuses on video and on-line commerce businesses. Accordingly, we expect that businesses that we may acquire in the future that we believe are complementary to this strategy will also be attributed to the Interactive Group.

The Starz Group consists primarily of our subsidiary Starz, LLC and approximately $1,035 million of cash, including subsidiary cash. Accordingly, the accompanying attributed financial information for the Starz Group includes these investments and the assets, liabilities, revenue, expenses and cash flows of that consolidated subsidiaries.

The Starz Group focuses primarily on video programming. Accordingly, we expect that businesses we may acquire in the future that we believe are complementary to this strategy will also be attributed to the Starz Group.

The Capital Group consists of all of our businesses not included in the Interactive Group or the Starz Group, including our consolidated subsidiaries Atlanta National League Baseball Club, Inc. and TruePosition, Inc. and certain cost and equity investments. Accordingly, the accompanying attributed financial information for the Capital Group includes these investments and the assets, liabilities, revenue, expenses and cash flows of these consolidated subsidiaries. In addition, we have attributed to the Capital Group all of our notes and debentures (and related interest expense) that have not been attributed to the Interactive Group or the Starz Group. See note 4 below for the debt obligations attributed to the Capital Group.

On February 25, 2010, Liberty announced that its board of directors had resolved to effect the following changes in attribution between the Capital Group and the Interactive Group, effective immediately (the "February Reattribution"):

•

the change in attribution from the Interactive Group to the Capital Group of Liberty's 14.6% ownership interest in Live Nation Entertainment, Inc.;

•

the change in attribution from the Capital Group to the Interactive Group of the following debt securities:

•: $469 million in principal amount of 4% Exchangeable Senior Debentures due 2029 (the "2029 Exchangeables");
•: $460 million in principal amount of 3.75% Exchangeable Senior Debentures due 2030 (the "2030 Exchangeables"); and

•: $492 million in principal amount of 3.5% Exchangeable Senior Debentures due 2031 (the "2031 Exchangeables", and together with the 2029 Exchangeables and the 2030 Exchangeables, the "Exchangeable Notes");

•: the change in attribution from the Capital Group to the Interactive Group of approximately $830 million in net taxable income to be recognized ratably in tax years 2014 through 2018 as a result of the cancellation in April 2009 of $400 million in principal amount of 2029 Exchangeables and $350 million in principal amount of 2030 Exchangeables; and
•: the change in attribution from the Capital Group to the Interactive Group of $807 million in cash.

The Liberty Media board determined that the February Reattribution would enable the Interactive Group to obtain long-term debt financing on better terms than would have been available to it in the capital markets at that time and improve the liquidity of the Interactive Group. In addition, the Interactive Group's generation of meaningful taxable income would better position it to utilize more directly and efficiently the tax benefits associated with the Exchangeable Notes. Previously, the Interactive Group was using these tax benefits, which were then attributed to the Capital Group, and compensating the Capital Group for such use. Lastly, the Liberty Media board believed that Liberty Media's equity interests in Live Nation Entertainment should be reattributed to the Capital Group in order to position it to take advantage of potential synergies associated with the Capital Group's interests in Sirius XM Radio.

In establishing the terms of the February Reattribution, the Liberty Media board reviewed, among other things, (i) a range of estimated values for the Exchangeable Notes (between $482 million and $526 million), which took into account the trading prices of the Exchangeable Notes and their unique tax attributes, among other things, and (ii) the estimated value of Liberty Media's equity interests in Live Nation Entertainment (approximately $298 million), which was based on the $12 per share offer price in Liberty Media's tender offer for additional shares of Live Nation during February 2010. Consistent with Liberty Media's Management and Allocation Policies, the Liberty Media board determined that the exchange of assets and liabilities between the two groups in the February Reattribution was completed on a fair value basis.

Liberty has reflected the February Reattribution prospectively. This change in attribution had no effect on the balance sheet and results of operations attributed to the Starz Group.

On September 16, 2010, Liberty Media's board of directors approved a change in attribution of Liberty Media's interest in Starz Media, LLC along with $15 million in cash from the Capital Group to the Starz Group, effective September 30, 2010 (the "Starz Media Reattribution"). As a result of the Starz Media Reattribution, an intergroup payable of approximately $54.9 million owed by the Capital Group to the Starz Group has been extinguished, and its Starz Group has become attributed with approximately $53.7 million in bank debt, interest rate swaps and any shutdown costs associated with the winding down of the Overture Films business. Notwithstanding the Starz Media Reattribution, the board determined that certain tax benefits relating to the operation of the Starz Media, LLC business by the Capital Group that may be realized from any future sale or other disposition of that business by the Starz Group will remain attributed to the Capital Group.

The Starz Media Reattribution enabled the Starz Group to acquire the complementary Starz Media business. Starz Entertainment had been engaging in mutually beneficial content distribution and programming arrangements with Starz Media, and it was inefficient for these arrangements to be treated as inter-group transactions. Accordingly, the Liberty Media board reattributed Starz

Media, and its related debt, from the Capital Group to the Starz Group. This also enabled the Capital Group to repay indebtedness it owed to the Starz Group without using any of its cash reserves.

In establishing the terms of the Starz Reattribution, the Liberty Media board considered, among other things, (i) a range of estimated values for the Starz Media assets (between $95 million and $122 million), (ii) the $53.7 million in Starz Media liabilities to be assumed and (iii) the $54.9 million payable owed by the Capital Group to the Starz Group. Consistent with Liberty Media's Management and Allocation Policies, the Liberty Media board determined that the exchange of assets and liabilities between the two groups in the Starz Reattribution was completed on a fair value basis.

Liberty has reflected the Starz Media Reattribution prospectively. This change in attribution has no impact on the balance sheet and results of operations attributed to the Interactive Group.

On February 9, 2011, Liberty Media's Board of Directors approved the change in attribution of (i) approximately $1.138 billion principal amount of Liberty Media LLC's 3.125% Exchangeable Senior Debentures due 2023 (the "TWX Exchangeable Notes"), (ii) 21,785,130 shares of Time Warner Inc. common stock, 5,468,254 shares of Time Warner Cable Inc. common stock and 1,980,425 shares of AOL, Inc. common stock, which collectively represent the basket of securities into which the TWX Exchangeable Notes are exchangeable (the "Basket Securities") and (iii) $263.8 million in cash from the Capital Group to the Interactive Group, effective immediately (the "TWX Reattribution"). The TWX Reattribution had no effect on the assets and liabilities attributed to the Starz Group, nor did it effect any change to the obligor of the TWX Exchangeable Notes, which remains Liberty Media LLC.

The Liberty Media board determined to effect the TWX Reattribution in light of the proposed split-off, to eliminate ambiguity regarding the terms of this reattribution and to better align the TWX Exchangeable Notes with the tracking stock group that has the strongest cashflow generation. The reattribution of the TWX Exchangeable Notes was necessary to complete the pending proposed split-off because the obligor thereunder, Liberty Media LLC, will remain with Liberty Media following that split-off. The Liberty Media board believed that waiting to complete this reattribution until an unknowable time when the conditions to the split-off would be satisfied was creating confusion in the marketplace over the terms of the pending reattribution, including the amount of cash to be reattributed. In addition, and irrespective of the split-off, the Liberty Media board believes the Interactive Group is best positioned to fulfill the obligations under the Exchangeable Notes given its strong cash flow and solid credit position. Accordingly, the Liberty Media board decided to complete the TWX Reattribution at its February 9, 2011 board meeting.

In establishing the terms of the TWX Reattribution, the Liberty Media board reviewed, among other things, (i) the principal amount of the TWX Exchangeable Notes, (ii) a range of values for tax liabilities associated with the delivery of the Basket Securities (between $162 million and $168 million), (iii) a range of values in payment for the risk that the Basket Securities are worth less than the face amount of the TWX Exchangeable Notes at the first date on which the TWX Exchangeable Notes can be redeemed, which is March 30, 2013 (between $36 million to $55 million), and (iv) the estimated value of the Basket Securities, using closing market prices on February 8, 2011 ($1.2 billion in the aggregate).

Any businesses that we may acquire in the future that are not attributed to the Interactive Group or the Starz Group will be attributed to the Capital Group.

While we believe the allocation methodology described above is reasonable and fair to each group, we may elect to change the allocation methodology in the future. In the event we elect to transfer assets or businesses from one group to the other, such transfer would be made on a fair value basis and would be accounted for as a short-term loan unless our board of directors determines to account for it as a long-term loan or through an inter-group interest.

(a): As of June 30, 2011, the Sirius Preferred Stock had a market value of $5,665 million based on the value of the common stock into which it is convertible.
(b): During June 2011 Liberty acquired an additional 5.5 million shares of Live Nation which put the ownership percentage greater than 20% of the outstanding voting shares. Due to the presumption that an entity with an ownership percentage greater than 20% has significant influence and no other factors would rebut that presumption the Company is accounting for the investment as an equity method affiliate. The Company has elected to record its share of earnings/losses for Live Nation on a three-month lag due to timelines considerations. Due to the relative insignificance of the share of losses for Live Nation in previous periods the Company has recorded their share of losses since the inception of the investment in the current year. Approximately $12 million of the losses recorded in the second quarter of 2011 relate to the prior years.

While we believe that this allocation method is reasonable and fair to each group, we may elect to change the allocation methodology or percentages used to allocate general and administrative expenses in the future.

(6): We have accounted for income taxes for the Interactive Group, the Starz Group and the Capital Group in the accompanying attributed financial information in a manner similar to a stand-alone company basis. To the extent this methodology differs from our tax sharing policy, differences have been reflected in the attributed net assets of the groups.
(7): The Liberty Interactive common stock, the Liberty Starz common stock and the Liberty Capital common stock have voting and conversion rights under our amended charter. Following is a summary of those rights. Holders of Series A common stock of each group are entitled to one vote per share and holders of Series B common stock of each group are entitled to ten votes per share. Holders of Series C common stock of each group, if issued, will be entitled to ¹/100th of a vote per share in certain limited cases and will otherwise not be entitled to vote. In general, holders of Series A and Series B common stock vote as a single class. In certain limited circumstances, the board may elect to seek the approval of only the holders of common stock related to our Interactive Group, our Starz Group or our Capital Group.

At the option of the holder, each share of Series B common stock is convertible into one share of Series A common stock of the same group. At the discretion of our board, the common stock related to one group may be converted into common stock of the same series that is related to one of our other groups.
