At the time of the episode, the Ewing Oil ownership structure was: J.R. & Bobby (35% each), Ray, Miss Ellie & Gary (10% each). If Cliff and Jamie won their lawsuit, the ownership structure would be: Cliff & Jamie (33.3% each), J.R. & Bobby (11.55% each), Ray, Miss Ellie & Gary (3.33% each). If Jack Ewing threw in with Jamie and Cliff, he would get half of Jamie's share (16.65%). Under his proposed agreement with J.R. and Bobby, he would get 10% while Bobby and J.R.'s share would drop to 30% each.
