The Denver-based Anschutz Co. said in a statement Tuesday night that it is beginning a process to sell the subsidiary known as AEG.

It's not immediately clear how far along the company is in the sale process, or whether it has entertained any offers, but the price for AEG could be well into the billions.

AEG's holdings also include pro soccer's LA Galaxy, part-ownership of the NBA's LA Lakers, and major entertainment and real estate holdings in downtown Los Angeles.
