Having these three figures presented as the summary invites that kind of equation. After all:
net income = revenue - expenses
But it looks like its a bit more complex, taking The Marvels as an example the $206.1m box office really converts to only $88m theatrical revenue for the studio. Then:
revenue = (theatrical + home entertainment + television and streaming)
218m = (88m + 40m + 90m)
expenses = (production costs + prints and ads + residuals and other distribution expenses + interest and overhead + participation)
455m = (270m + 110m + 21m + 54m + 0m)
net income = revenue - expenses
-237m = 218m - 455m
