Last week, Sawiris and Edens were ranked fifth most-wealthiest owners in the Premier League with a combined net worth of around £5billion.
Smith prides himself on having good relations with the club's hierarchy and said: "The relationship with the owners and CEOs is one of the most important.
"I can honestly say out of all the clubs I've worked with - Leyton Orient, Walsall, Brentford and Aston Villa - I could go out for dinner with all of the CEOs and owners now because, at the end of the day, it's their club.
"You have to have a good relationship with them. You're not always a yes man. You've got your philosophy and your reasons why you do things but they're ultimately the ones who do things and pay the money. If you get into an argument with an owner, there's only one winner."
