Unless Liberty buys the remaining Sirius shares -- it will not impact Sirius shareholders at all, unless they do a much more complicated deal.
The difference is it's not a spin-off, but rather a split-off. The former is a distribution, while the latter is an exchange... usually done on a tax-free basis.
A classic example of this is what Liberty Media is doing right now with DTV.... the Liberty holds a majority stake in DTV -- and now they are doing a split-off. So what they are doing is creating a new company called the DirecTV Group... where all shareholders of the current DTV will get 1 share of the new company, in exchange for each 1 share they currently hold of the old company; while at the same time, Liberty Entertainment shareholders will receive 1.1111 shares of the new company, in exchange for each 1 share they hold of the Liberty Entertainment tracking stock. Thus the company splits-off from Liberty Media.
Liberty Media will redeem 90% of the Liberty Entertainment tracking stock, in exchange for 100% of the stock a new company called LEI -- which will then merge with DTV forming the new DirecTV Group.
DirecTV Group would then be a seperate company from Liberty -- wholly owned by its shareholders. But if I recall correctly, Liberty will still have a minority stake in the new company via their own stock in their own shares.
It's complicated -- and don't think of it as a buyout or a spin off. It's a split off -- or an exchange... which may or may not involve Sirius shareholders at the time.
Regardless, it won't be happening any time soon.
