With the news today that Yuriorkis Gamboa might be going to Mayweather Promotions, many people have been asking a number of questions about this organization. First of all, Mayweather Promotions is a limited liability company (an LLC) in Nevada. Being a LLC in Nevada has a bunch of tax advantages including no personal income tax, no corporate tax, no gift tax, and no unitary tax. There are also liability advantages for being located in Nevada including the fact that officers (C-level, presidents, vice presidents, etc.) cannot be sued as an individual for actions tied to the company, except for outright fraud. There are a bunch of business-friendly privacy laws in Nevada as well. I assume that there is some liability and tax advantages for funneling Mayweather's cash through Mayweather Promotions, and that's why it exists.
Now you may have heard either Scott or many other people say that Mayweather promotions is not a licensed promotional company as can be seen here. In Nevada, you have to go through a licensing procedure before the Nevada State Athletic Commission would recognize a LLC which are listed on the NSAC website. Essentially, there is a bunch of paperwork to fill out and there is a sizable fee to pay to NSAC.
It is not a difficult procedure but once you become a licensed promoter, the company becomes responsible for a ton of logistics related to putting on a fight. The promotional company is responsible for paying officials, drug and steroid testing, primary medical insurance for the fighter, making sure an ambulance is at the arena, paying ticket fees, paying television fees, submitting the appropriate paperwork, scheduling the proper events, getting the proper licenses, hire a ring announcer, make sure the fighters have appropriately stocked dressing rooms, a proper scale for the weigh-in, supplying approved gloves, issuing credentials, and giving officials parking passes. Whew, that's a whole lot of stuff, and it's why Mayweather Promotions does not want to become a licensed promoter.
I would assume that Mayweather Promotions would need to hire a bunch of people to make sure all of these logistical issues are appropriately handled. Basically, they would need to have an actual business and I don't think Floyd has any interest in the logistics of a fight.
Whenever a "Mayweather Promotions" fighter like Jesse Vargas fights, the promoter responsible for these logistics is Golden Boy Promotions. This is why Scott and others frequently call Mayweather Promotions a poster and nothing more.
Hopefully this clarifies all the questions surrounding Mayweather Promotions.
