What if you do not have one production company but several? How do you list that in IMDB scorecard?

I want to put video trailers on my film projects main page. Says I need to verify I am a business rep for the film/production company that made the films. What if you do not have one production company but several? How do you list that in the projects, in my contacts section on the left side of the page under my headshot, and how to do this on IMDB scorecard?
