Bitter rivalries may spawn awkwards moments for moguls attending Sun Valley

Deal combatants from Fox, Disney and Comcast may all be there

When the billionaires and corporate moguls converge on Idaho’s Sun Valley resort in early July for Allen & Co.’s annual conference, the investment bank may need to give a lot of thought to the seating chart.
 
Quite a few attendees expected to be at this year’s confab are at each other’s throats. Take CBS Corp. Chief Executive Officer Les Moonves. He’s locked in a legal fight for control of the broadcast company with top shareholder Shari Redstone, who is also on the guest list.
 
Comcast Corp. Chairman Brian Roberts is invited as well. He’s battling Walt Disney Co.
