http://www.azcentral.com/story/mone...ew-york-based-sirius-xm-holdings-inc/6411423/ ENGLEWOOD, Colo. â€“ Liberty Media is dropping its bid to buy the rest of the satellite radio provider Sirius. The move disclosed late Thursday comes as Liberty Media Corp., which is controlled by billionaire John Malone, takes steps to create two new tracking stock groups for its business. One will be called Liberty Media Group and the other will be Liberty Broadband Group. Liberty Media said that because of the tracking stock distribution, it is withdrawing its offer for the rest of New York-based Sirius XM Holdings Inc. Liberty Media owns 53 percent of Sirius stock. In January, Liberty announced a complex proposal that would have allowed it to obtain full ownership of Sirius. The deal would've valued Sirius at nearly $23 billion. Liberty Media President and CEO Greg Maffei said in a statement that the company may hold further discussions with Sirius depending on market conditions. Sirius XM has built the world's largest pay-radio service with 25.6 million subscribers. The creation of the new tracking stocks still needs approval from Liberty Media shareholders. But Liberty expects it to be in place by the third quarter. Liberty Media said that the Liberty Broadband Group is expected to include its interest in the cable TV provider Charter Communications Inc. as well as its interest in another cable company Time Warner Cable Inc. and its subsidiary TruePosition Inc. It will also include a note obligation from Liberty Broadband Group to Liberty Media Group, a call option liability associated with Liberty's Time Warner Cable shares and liabilities at TruePosition. Englewood, Colo.-based company Liberty Media said the Liberty Media Group will include the rest of its businesses, assets and liabilities. That would include Liberty's subsidiary Sirius XM Holdings Inc. Shares of Sirius XM Holdings slipped a penny to $3.36 in premarket trading Friday. Liberty Media's Class A shares rose $9,57, or 7.6 percent, to $135.71 in premarket trading.
