What are the typical rates or tariffs for sponsors at an ATP tennis
tournament and what benefits would they get for their sponsorship
money? For instance, what exposure on the court, advert in the
tournament program/magazine, logos adverts on the tournament website
etc.

This might help.

Thanks but the ATP you have dug up is not the ATP one we want, we want
ATP - Association of Tennis Professionals whereas your ATP is
Association of Test Publishers (whatever that is!. thanks though for
trying

I hope this website answers your questions.

Thanks to cshtennis-ga but yes, this was the first place we looked.
There are no rates here

Rates seem to fluctuate alot depending on how much recognition you
want to receive from sponsoring the ATP.  Some of the big name
sponsors like Mercedes Benz and Sony Ericsson pay alot more and
receive alot more through recogntion on tv and other media sources.

An example of an agreement can befound on this website.

As for the benefits of sponsoring the ATP they can be found in the
website posted earlier.

Hope this somewhat answers your question.

Many thanks cshtennis-ga but again this is a site that alludes to
stuff but you get no rate card or check list of advantages...
