A source close to the show outlined to The Huffington Post the outcome of the negotiation's areas of dispute:
AMC dropped its demand for a $1.5 million per season budget cut; the preserved money means in part that Weiner will no longer be required to cut two significant actors per season. Instead, characters will be cut if it suits the show creatively.
The network insisted that the show cut two minutes per episode for more advertising time; the contract calls for the first and last episode of the show to be the normal 47 minutes. For episodes 2-11, they will initially air as 45 minute episodes, and Weiner's "Final Cut" will be available digitally 8 days later.
Additionally, product integration policy will remain the same; AMC had wanted more transparency in placements, requesting the ability for companies to publicize that their products appeared on the show.
