It seems a mystery. The last time they met, the Association of Talent Agents offered to share backend television packaging fees with the Writers Guild of America, but that April 12 offer was only about one percent, a figure ostensibly so meager as to defy explanation. Negotiations cratered and the WGA filed suit days later. Why would any negotiator propose such a minuscule amount? Why didn’t the agencies propose, say, 25 percent as a reasonable opener?
