How Disney Bought LFL
Really interesting story there. Fills in a lot of details about just when Lucas decided to get the band back together for Episode 7, when Disney came on board, etc. Definitely a good read.
I'm not an investment banker, but it looks like Disney got a steal compared to what they paid for Pixar and Marvel. They paid $7 billion and $4 billion for Pixar and Marvel, respectively, while paying $4 billion for Lucasfilm.
Page 3 of the article shows the cash flows at the three companies at the time of purchase and Lucasfilm generates significantly more operating income than Marvel.
