We and our subsidiaries are each responsible for our respective liabilities. Holders of Liberty SiriusXM common stock, Liberty Braves common stock and Liberty Formula One common stock are holders of our common stock and are subject to risks associated with an investment in our company and all of our businesses, assets and liabilities. The issuance of Liberty SiriusXM common stock, Liberty Braves and Liberty Formula One common stock does not affect the rights of our creditors.

Notes to Attributed Financial Information (Continued)

(unaudited)

(1) 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. While the Liberty SiriusXM Group, Liberty Braves Group (the “Braves Group”) and Formula One 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. Therefore, the Liberty SiriusXM Group, Braves Group and Formula One Group do not represent separate legal entities, but rather represent those businesses, assets and liabilities that have been attributed to each respective group. Holders of tracking stock have no direct claim to the group's stock or assets and therefore, do not own, by virtue of their ownership of a Liberty tracking stock, any equity or voting interest in a company, such as Sirius XM Holdings Inc. (“SIRIUS XM”), Formula 1 or Live Nation Entertainment, Inc. (“Live Nation”), in which Liberty holds an interest and that is attributed to a Liberty tracking stock group, such as the Liberty SiriusXM Group or the Formula One Group. Holders of tracking stock are also 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 Liberty SiriusXM Group is comprised of our consolidated subsidiary, SIRIUS XM, corporate cash, Liberty’s 2.125% Exchangeable Senior Debentures due 2048 and its margin loan obligation incurred by a wholly-owned special purpose subsidiary of Liberty. As of March 31, 2018, the Liberty SiriusXM Group has cash and cash equivalents of approximately $658 million, which includes $79 million of subsidiary cash.

The Braves Group is comprised of our consolidated subsidiary, Braves Holdings, LLC (“Braves Holdings”), which indirectly owns the Atlanta Braves Major League Baseball Club (“ANLBC”) and certain assets and liabilities associated with ANLBC’s stadium and mixed use development project (the “Development Project”) and cash. As of March 31, 2018, the Braves Group has cash and cash equivalents of approximately $114 million, which includes subsidiary cash.

The Formula One Group is comprised of all of the businesses, assets and liabilities of Liberty other than those specifically attributed to the Liberty SiriusXM Group or the Braves Group, including Liberty’s interests in Formula 1 and Live Nation Entertainment, Inc. (“Live Nation”), a minority equity investment in Time Warner Inc. (“Time Warner”),  cash, an intergroup interest in the Braves Group, Liberty’s 1.375% Cash Convertible Notes due 2023 and related financial instruments,  Liberty’s 2.25% Exchangeable Senior Debentures due 2046 and Liberty’s 1% Cash Convertible Notes due 2023. As of March 31, 2018, the Formula One Group has cash and cash equivalents of approximately $270 million, which includes $140 million of cash held by Formula 1.

The number of notional shares representing the intergroup interest held by the Formula One Group is 9,084,940, representing a 15.1% intergroup interest in the Braves Group as of March 31, 2018. The intergroup interest is a quasi-equity interest which is not represented by outstanding shares of common stock; rather, the Formula One Group has an attributed value in the Braves Group which is generally stated in terms of a number of shares of stock issuable to the Formula One Group with respect to its interest in the Braves Group. Each reporting period, the notional shares representing the intergroup interest are marked to fair value. The change in fair value is recorded in the Unrealized gain (loss) on intergroup interest line item in the unaudited attributed condensed consolidated statements of operations. The Formula One Group’s intergroup interest is reflected in the Investment in intergroup interest line item, and the Braves Group liability for the intergroup interest is reflected in the Redeemable intergroup interest line item in the unaudited attributed condensed consolidated balance sheets. Both accounts are presented as noncurrent, as there are currently no plans for the settlement of the intergroup interest. Appropriate eliminating entries are recorded in the Company’s condensed consolidated financial statements.

As the notional shares underlying the intergroup interest are not represented by outstanding shares of common stock, such shares have not been officially designated Series A, B or C Liberty Braves common stock. However, Liberty has assumed that the notional shares (if and when issued) would be comprised of Series C Liberty Braves common stock in order to not dilute voting percentages. Therefore, the market price of Series C Liberty Braves common stock is used for the quarterly mark-to-market adjustment through the unaudited attributed condensed consolidated statements of operations.

Notes to Attributed Financial Information (Continued)

(unaudited)

The intergroup interest will remain outstanding until the redemption of the outstanding interest, at the discretion of the Company’s Board of Directors, through transfer of securities, cash and/or other assets from the Braves Group to the Formula One Group.  

For information relating to investments in debt and equity securities, investments in affiliates accounted for using the equity method and debt, see notes 8, 9 and 11, respectively, of the accompanying condensed consolidated financial statements.

(2) Cash compensation expense for our corporate employees is allocated among the Liberty SiriusXM Group, Braves Group and the Formula One Group based on the estimated percentage of time spent providing services for each group. On an annual basis estimated time spent is determined through an interview process and a review of personnel duties unless transactions significantly change the composition of companies and investments in either respective group which would require a timelier reevaluation of estimated time spent. Other general and administrative expenses are charged directly to the groups whenever possible and are otherwise allocated based on estimated usage or some other reasonably determined methodology. Following the Recapitalization, stock compensation related to each tracking stock is calculated based on actual awards outstanding.

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.

(3) Except for the intergroup arrangements regarding the securities held by the Formula One Group pledged as collateral pursuant to a loan at the Braves Group as discussed in note 11 of the accompanying condensed consolidated financial statements, the intergroup balance at March 31, 2018 and December 31, 2017 is primarily a result of timing of tax benefits.

(4) The Liberty SiriusXM common stock, Liberty Braves common stock and Liberty Formula One common stock have voting and conversion rights under our restated 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 are 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 the holders of only Series A and Series B Liberty SiriusXM common stock, only Series A and Series B Liberty Braves common stock, or only Series A and Series B Liberty Formula One common stock.

At the option of the holder, each share of Series B common stock of each group will be 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 another other group.
