The figures from court documents must include his income with everything figured in because the top WWE talents have a $1 million downside guarantee.
Even with merchandise sales figured in, the numbers for Orton seem a bit high. One person with familiarity with such numbers said the report of Orton making $291,666 per month is "laughable" and that Orton may have had some specific months that big when he was headlining top pay-per-views but his guaranteed contract is nowhere near that level.
It’s pretty well known that the top tier of talents in the company earn $1 million downside and nobody is contracted for more money except the special attractions like The Rock or Brock Lesnar.
